 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The unaudited condensed consolidated financial
 statements have been prepared in accordance with generally accepted
 accounting principles (&amp;#x201C;GAAP&amp;#x201D;) in the United States
 (&amp;#x201C;U.S.&amp;#x201D;) and applicable rules and regulations of the
 Securities and Exchange Commission (&amp;#x201C;SEC&amp;#x201D;) regarding
 interim financial reporting. These financial statements have been
 prepared on the same basis as the Company&amp;#x2019;s annual financial
 statements and, in the opinion of management, reflect all normal
 recurring adjustments, except as otherwise disclosed, that are
 necessary for a fair statement of the Company&amp;#x2019;s results for
 the interim periods presented. These interim financial results are
 not necessarily indicative of results expected for the full fiscal
 year or for any subsequent interim period.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 7pt" align="justify"&gt;The condensed consolidated financial statements and
 related financial information should be read in conjunction with
 the audited financial statements and the related notes included in
 the Company&amp;#x2019;s Annual Report on Form &lt;font style="WHITE-SPACE: nowrap"&gt;10-K&lt;/font&gt; for the year ended
 December&amp;#xA0;31, 2016. Certain information and footnote
 disclosures normally included in financial statements prepared in
 accordance with U.S. GAAP have been condensed or omitted. The
 condensed consolidated balance sheet as of December&amp;#xA0;31, 2016
 was derived from the Company&amp;#x2019;s audited financial statements
 for the year ended December&amp;#xA0;31, 2016, but does not include all
 disclosures required by U.S. GAAP as permitted by the applicable
 rules and regulations of the SEC regarding interim financial
 reporting. However, the Company believes the disclosures are
 adequate to make the information presented not misleading. The
 condensed consolidated financial statements include the accounts of
 the Company and its wholly owned subsidiaries. All intercompany
 transactions and balances have been eliminated in
 consolidation.&lt;/p&gt;

 lawsuit alleging violations of federal securities laws was filed in
 the U.S. District Court for the Northern District of California,
 captioned&lt;i&gt;&amp;#xA0;Monachelli v. Hortonworks, Inc&lt;/i&gt;.,
 Case&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;3:16-cv-00980-SI.&amp;#xA0;The&lt;/font&gt;&lt;/font&gt;&lt;/font&gt;&amp;#xA0;lawsuit
 names as defendants the Company, Robert G. Bearden, and Scott J.
 Davidson.&amp;#xA0;Plaintiffs allege that the defendants violated
 Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 by
 allegedly making materially false and misleading statements
 regarding the Company&amp;#x2019;s business and operations.&amp;#xA0;On
 June&amp;#xA0;1, 2016, the court entered an order appointing a lead
 plaintiff and lead counsel. On July&amp;#xA0;28, 2016, the lead
 plaintiff and another named plaintiff filed an amended complaint
 seeking to represent a class of persons who purchased or otherwise
 acquired Hortonworks&amp;#x2019; securities between August&amp;#xA0;5, 2015
 and January&amp;#xA0;15, 2016, inclusive, and seeking class
 certification, an award of unspecified compensatory damages, an
 award of reasonable costs and expenses, including attorneys&amp;#x2019;
 fees, and other further relief as the Court may deem just and
 proper. On December&amp;#xA0;5, 2016, the court granted
 defendants&amp;#x2019; motion to dismiss the amended complaint, with
 leave to amend. The parties thereafter engaged in settlement
 negotiations and have agreed to a class-wide settlement that would
 not have a material effect on the Company&amp;#x2019;s financial
 statements. On October&amp;#xA0;10, 2017, the Court issued an order and
 final judgment granting approval of the proposed settlement and
 dismissing the matter with prejudice.&lt;/p&gt;

 filed in the Court of Chancery of the State of Delaware,
 captioned&amp;#xA0;&lt;i&gt;Steinberg v. Bearden, et al.&lt;/i&gt;,
 Case No.&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;2017-0286-AGB,&lt;/font&gt;&amp;#xA0;purportedly
 filed by a Hortonworks shareholder on behalf of the Company against
 certain of the Company&amp;#x2019;s directors and executive officers.
 The derivative complaint alleges that the defendants breached their
 fiduciary duties to the Company and allegedly made false or
 misleading statements regarding the Company&amp;#x2019;s business and
 operations. The derivative action includes claims for, among other
 things, unspecified damages in favor of the Company, corporate
 actions to purportedly improve the Company&amp;#x2019;s corporate
 governance, and an award of costs and expenses to the derivative
 plaintiffs, including attorneys&amp;#x2019; fees. On July&amp;#xA0;3, 2017,
 defendants filed a motion to dismiss the complaint. Because the
 action is in the early stages of the litigation process, the
 Company is unable to assess whether any loss or adverse effect on
 its financial condition is probable or remote or to estimate the
 range of potential loss, if any.&lt;/p&gt;

 &lt;font style="white-space:nowrap"&gt;two-year&lt;/font&gt; senior secured
 revolving credit agreement with Silicon Valley Bank (the
 &amp;#x201C;Bank&amp;#x201D;) on November&amp;#xA0;2, 2016 and amended such
 agreement on June&amp;#xA0;26, 2017 and September&amp;#xA0;22, 2017 (as
 amended, the &amp;#x201C;Credit Agreement&amp;#x201D;). Amounts outstanding
 under the Credit Agreement are payable on or before
 November&amp;#xA0;2, 2018 and will accrue interest per annum at a rate
 equal to the Bank&amp;#x2019;s prime rate plus 0.50&amp;#xA0;percent. Any
 outstanding loans drawn under the Credit Agreement may be paid at
 any time prior to maturity. Pursuant to the terms of the Credit
 Agreement, the Company agreed to pay an annual facility fee equal
 to 0.50&amp;#xA0;percent of the aggregate amount of the revolving
 credit facility commitments and an unused line fee of 0.35
 percent&amp;#xA0;per annum on the unused commitments. The Credit
 Agreement currently has no subsidiary guarantors.&lt;/p&gt;
 &lt;p style="margin-top:9pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" align="justify"&gt;The Credit Agreement contains customary reporting,
 affirmative and negative covenants, including negative covenants
 imposing limitations on, among other things, the ability of the
 Company and its subsidiaries to incur additional indebtedness,
 grant liens, consummate asset sales, make certain investments and
 declare or make dividends or repurchase its stock. It also contains
 certain financial covenants that require the Company to maintain a

 &lt;b&gt;7. NET LOSS PER SHARE OF COMMON STOCK&lt;/b&gt;&lt;/p&gt;
 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" align="justify"&gt;Basic net loss per share of common stock is
 calculated by dividing net loss by the weighted-average number of
 shares of common stock outstanding during the period, less
 restricted common stock and common stock issued that is subject to
 repurchase, and excludes any dilutive effects of share-based
 awards. Diluted net loss per share of common stock is computed
 giving effect to all potential dilutive shares of common stock. As
 the Company had net losses for the three and nine months ended
 September&amp;#xA0;30, 2017 and 2016, all potential shares of common
 stock were determined to be anti-dilutive.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt" align="justify"&gt;Where applicable, the Company uses quoted market
 prices in active markets for identical assets to determine fair
 value. This pricing methodology applies to Level&amp;#xA0;1
 investments, which are composed of money market funds. If quoted
 prices in active markets for identical assets are not available,
 then the Company uses quoted prices for similar assets or inputs
 other than quoted prices that are observable, either directly or
 indirectly. These investments are included in Level&amp;#xA0;2 and
 consist of U.S. government securities, certificates of deposit,
 commercial paper and corporate notes and bonds. Commercial paper is
 valued using market prices, if available, adjusting for accretion
 of the purchase price to face value at maturity. The carrying
 amounts of accounts receivable, prepaid expenses and other current
 assets, accounts payable, accrued compensation and benefits and
 accrued expenses and other current liabilities approximate fair
 value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt" align="justify"&gt;The Company entered into a three-year,
 $2.5&amp;#xA0;million promissory note receivable with a third-party
 service provider in February 2015, which bears interest at four
 percent per annum. The promissory note receivable was valued on a
 &lt;font style="WHITE-SPACE: nowrap"&gt;non-recurring&lt;/font&gt; basis and
 was classified as &lt;font style="WHITE-SPACE: nowrap"&gt;&lt;font style="WHITE-SPACE: nowrap"&gt;held-to-maturity&lt;/font&gt;&lt;/font&gt; within
 long-term investments. During the year ended
 December&amp;#xA0;31,&amp;#xA0;2016,&amp;#xA0;the Company recognized an
 impairment charge of $2.7&amp;#xA0;million in operating expenses
 related to the promissory note and related interest receivable as
 the Company determined it was probable the promissory note and
 related interest receivable were unrecoverable due to the
 third-party service provider&amp;#x2019;s illiquidity and unfavorable
 rate of cash use.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt" align="justify"&gt;A financial instrument&amp;#x2019;s categorization
 within the valuation hierarchy is based upon the lowest level of
 input that is significant to the fair value measurement. The
 Company&amp;#x2019;s assessment of the significance of a particular
 input to the fair value measurement in its entirety requires
 management to make judgments and consider factors specific to the
 asset or liability. During the nine months ended September&amp;#xA0;30,
 2017 and the year ended December&amp;#xA0;31, 2016, the Company did not
 make any transfers between Level&amp;#xA0;1 or Level&amp;#xA0;2
 investments.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt" align="justify"&gt;Gross unrealized gains and losses were not material
 as of September&amp;#xA0;30, 2017 and December&amp;#xA0;31, 2016. Realized
 gains and losses were not material for both the three and nine
 months ended September&amp;#xA0;30, 2017 and 2016. As of
 September&amp;#xA0;30, 2017 and December&amp;#xA0;31, 2016, there were no
 securities that were in an unrealized loss position for more than
 12 months.&lt;/p&gt;

 &lt;p style="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" align="justify"&gt;The effective tax rate for the three months ended
 September&amp;#xA0;30, 2017 was (0.9) percent compared to (0.5) percent
 for the same period of 2016. The effective tax rate for the nine
 months ended September&amp;#xA0;30, 2017 was (0.7) percent compared to
 (0.4) percent for the same period of 2016.&amp;#xA0;The income tax
 expense for the three and nine months ended September&amp;#xA0;30, 2017
 and 2016 was determined based upon estimates of the Company&amp;#x2019;s
 effective income tax rates in various jurisdictions. The difference
 between the consolidated effective income tax rate and the U.S.
 federal statutory rate is primarily attributable to state income
 taxes, foreign income taxes, the effect of certain permanent
 differences and full valuation allowance against net deferred tax
 assets.&lt;/p&gt;

 and Other (Topic 350): Simplifying the Test for Goodwill
 Impairment&lt;/i&gt;, which eliminates Step 2 from the goodwill
 impairment test. The standard requires an entity to perform its
 annual, or interim, goodwill impairment test by comparing the fair
 value of a reporting unit with its carrying amount. An entity
 should recognize an impairment charge for the amount by which the
 carrying amount exceeds the reporting unit&amp;#x2019;s fair value. In
 addition, the ASU&amp;#xA0;eliminates the requirements for any
 reporting unit with a zero or negative carrying amount to perform a
 qualitative assessment.&amp;#xA0;The ASU is effective for public
 companies for fiscal years beginning after December&amp;#xA0;15, 2019.
 Early adoption is permitted. The Company does not anticipate

 606)&amp;#xA0;&lt;/i&gt;(the &amp;#x201C;new standard&amp;#x201D;), which
 will replace most existing revenue recognition guidance in U.S.
 GAAP when it becomes effective. The new standard requires an entity
 to recognize the amount of revenue to which it expects to be
 entitled upon transfer of promised goods or services to customers.
 The new standard&amp;#xA0;defines a five-step process in order to
 achieve this core principle, which may require the use of judgment
 and estimates, and also requires expanded qualitative and
 quantitative disclosures relating to the nature, amount, timing and
 uncertainty of revenue and cash flows arising from contracts with
 customers, including significant judgments and estimates used.&lt;/p&gt;

 (i)&amp;#xA0;a full retrospective approach for all periods presented or
 (ii)&amp;#xA0;a modified retrospective approach with the cumulative
 effect of initially applying the new standard recognized at the
 date of initial application and providing certain additional
 disclosures. The Company is adopting the new standard as of
 January&amp;#xA0;1, 2018 using the modified retrospective approach. The
 Company&amp;#x2019;s decision was based on a number of factors such as
 the significance of the impact of the new standard on the
 Company&amp;#x2019;s financial results, system readiness, including that
 of software procured from third-party providers, and the
 Company&amp;#x2019;s ability to accumulate and analyze the information
 necessary to assess the cumulative effect of the new standard
 through January&amp;#xA0;1, 2018.&lt;/p&gt;

 the new standard on its accounting policies, processes and system
 requirements. The Company has assigned internal resources in
 addition to the engagement of third-party service providers to
 assist in the evaluation and to provide periodic updates to
 management and the Audit Committee. In evaluating the risks
 associated with the adoption of the new accounting standard, the
 Company has identified and scoped the different revenue streams and
 reviewed contracts in each revenue stream for terms and conditions
 that could result in different accounting treatment. Furthermore,
 the Company has made and will continue to make investments in
 systems to enable timely and accurate reporting under the new
 standard. While the Company continues to assess all potential
 impacts under the new standard, significant impacts are expected to
 the timing and amount of support subscription and professional
 services revenue recognized, as well as the capitalization and
 amortization of contract acquisition costs. In addition,
 the&amp;#xA0;Company will&amp;#xA0;update&amp;#xA0;certain disclosures,&amp;#xA0;as
 applicable,&amp;#xA0;included in its filings pursuant to the Securities
 Exchange Act of 1934, as amended, to meet the requirements of the
 new standard.&lt;/p&gt;

 recognition guidance, the Company has concluded it has not
 established vendor-specific objective evidence of fair value
 (&amp;#x201C;VSOE&amp;#x201D;) for support subscriptions and professional
 services offerings in multiple-element arrangements where support
 subscriptions are sold with professional services. The Company
 recognizes revenue on a ratable basis over the period beginning
 when both the support subscription and professional services have
 substantially commenced, and ending at the conclusion of the
 support subscription or professional services period, whichever is
 longer. The new standard, which does not retain the concept of
 VSOE, requires an evaluation of whether support subscriptions and
 professional services are distinct performance obligations, and
 therefore should be separately recognized as the respective
 performance obligations are satisfied based on the standalone
 selling price for each performance obligation, which may not be on
 a ratable basis. Based on the Company&amp;#x2019;s evaluation under the
 new standard, the timing of revenue recognition will change
 significantly for professional services bundled in multiple-element
 arrangements and currently recognized ratably due to lack of VSOE
 for support subscriptions. In particular, professional services
 revenue will be recognized in an earlier period and over a shorter
 timeframe under the new standard as the services are delivered
 compared to the Company&amp;#x2019;s current accounting policy under the
 existing standards and guidance. Also, the timing of recognition
 will change to begin in an earlier period for some support
 subscriptions bundled in multiple-element arrangements compared to
 the Company&amp;#x2019;s current accounting policy for multiple-element
 arrangements whereby recognition generally begins when both the
 support subscription and professional services have substantially
 commenced.&lt;/p&gt;

 has also considered the impact of the guidance in Accounting
 Standards Codification&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;(&amp;#x201C;ASC&amp;#x201D;)&amp;#xA0;340-40&lt;/font&gt;&lt;i&gt;,&lt;/i&gt;&lt;i&gt;&amp;#xA0;Other
 Assets and Deferred Costs; Contracts with Customers&lt;/i&gt;, and the
 interpretations of the FASB TRG for Revenue Recognition from their
 November&amp;#xA0;7, 2016 meeting with respect to the capitalization
 and amortization of incremental costs of obtaining a contract
 (&lt;i&gt;e.g.&lt;/i&gt;, sales commissions). For contracts with an expected
 duration greater than one year, the new standard requires the
 capitalization of incremental costs that the Company incurs to
 obtain a contract with a customer that it would not have incurred
 if the contract had not been obtained, provided the Company expects
 to recover the costs. Such capitalized costs are then to be
 amortized on a systematic basis that is consistent with the
 transfer to the customer of the services to which such costs
 relate, and the amortization period may extend beyond the initial
 contract term if renewal commissions on expected renewals are not
 commensurate with the commission on the initial contract. Under the
 Company&amp;#x2019;s current accounting policy, incremental costs
 incurred to obtain a contract are expensed when incurred. Thus, the
 application of the new standard will result in a significant change
 to the Company&amp;#x2019;s current accounting policy for contract
 acquisition costs, which will result in the Company recognizing the
 expense for contract acquisition costs in a different period, and
 over a longer period, compared to the Company&amp;#x2019;s current
 practice under the existing standards and guidance.&lt;/p&gt;

 issued&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;ASU&amp;#xA0;No.&amp;#xA0;2016-09,&lt;/font&gt;&lt;i&gt;&amp;#xA0;Compensation-Stock
 Compensation (Topic 718): Improvements to Employee Share-Based
 Payment Accounting&lt;/i&gt;, which simplifies several aspects of the
 accounting for employee share-based payment transactions for both
 public&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;and&amp;#xA0;non-public&amp;#xA0;entities,&lt;/font&gt;&amp;#xA0;including
 the accounting for income taxes, forfeitures and statutory tax
 withholding requirements, as well as classification in the
 statements of cash flows. The ASU is effective for public companies
 for fiscal years beginning after December&amp;#xA0;15, 2016, including
 interim periods within those fiscal years. The Company adopted the
 new standard as of January&amp;#xA0;1, 2017. As a result of adopting
 this standard, the Company made an accounting policy election to
 account for forfeitures as they occur. This change was applied on a
 modified retrospective basis, resulting in a cumulative-effect
 adjustment increasing accumulated deficit by $0.7&amp;#xA0;million as
 of January&amp;#xA0;1, 2017.&lt;/p&gt;

 recognized the excess tax benefits of stock-based compensation
 expense as&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;additional&amp;#xA0;paid-in&amp;#xA0;capital,&lt;/font&gt;&amp;#xA0;and
 tax deficiencies of stock-based compensation expense in the income
 tax provision or as&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;additional&amp;#xA0;paid-in&amp;#xA0;capital&lt;/font&gt;&amp;#xA0;to
 the extent that there were sufficient recognized excess tax
 benefits previously recognized. As a result of the prior
 requirement that excess tax benefits reduce taxes payable prior to
 being recognized as an increase in
 additional&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt;&amp;#xA0;capital, the
 Company had not recognized certain deferred tax assets (all tax
 attributes such as loss or credit carryforwards) that could be
 attributed to tax deductions related to equity compensation in
 excess of compensation recognized for financial reporting.&lt;/p&gt;

 adopted a change in accounting policy in accordance with the new
 standard to account for excess tax benefits and tax deficiencies as
 income tax expense or benefit, treated as discrete items in the
 reporting period in which they occur, and to recognize previously
 unrecognized deferred tax assets that arose directly from (or the
 use of which was postponed by) tax deductions related to equity
 compensation in excess of compensation recognized for financial
 reporting. The change was applied on a modified retrospective
 basis; no prior periods were restated as a result of this change in
 accounting policy.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: &amp;quot;Times New Roman&amp;quot;; WHITE-SPACE: normal; WORD-SPACING: 0px; TEXT-TRANSFORM: none; FONT-WEIGHT: normal; COLOR: rgb(0,0,0); FONT-STYLE: normal; ORPHANS: 2; WIDOWS: 2; MARGIN-TOP: 8pt; LETTER-SPACING: normal; TEXT-INDENT: 0px; font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial" align="justify"&gt;The new standard also eliminates the requirement
 that excess tax benefits be realized as a reduction in current
 taxes payable before the associated tax benefit can be recognized
 as an increase in additional&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt;&amp;#xA0;capital.
 Approximately $38.4&amp;#xA0;million of federal net operating losses
 and $24.4&amp;#xA0;million of state net operating losses (none of which
 were included in the deferred tax assets recognized in the
 condensed consolidated balance sheet as of December&amp;#xA0;31, 2016)
 have been attributed to tax deduction for stock-based compensation
 expense in excess of the related book expense. Under the new
 standard, these previously unrecognized deferred tax assets were
 recognized on a modified retrospective basis as of January&amp;#xA0;1,
 2017. The U.S. federal and state net operating losses recognized as
 of January&amp;#xA0;1, 2017, as described above, have been offset by a
 valuation allowance. As a result, there
 was&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;no&amp;#xA0;tax-related&amp;#xA0;cumulative-effect&lt;/font&gt;&amp;#xA0;to
 accumulated deficit.&lt;/p&gt;

(the &amp;#x201C;Company&amp;#x201D;) was
 incorporated in Delaware in 2011 and is an industry-leading
 innovator that creates, distributes and supports a new class of
 enterprise data management software solutions built upon open
 source technology. The Company&amp;#x2019;s customers use its
 enterprise-scale data management platforms and services to maximize
 the value of their data by generating business insights and
 supporting their predictive and real-time analytic

 (&amp;#x201C;HDP&amp;#x201D;&lt;sup style="FONT-SIZE: 11px; VERTICAL-ALIGN: top"&gt;&amp;#xAE;&lt;/sup&gt;) is a
 foundational element of the Company&amp;#x2019;s offerings. HDP is an
 enterprise-scale data management platform built upon open source
 software including Apache&lt;sup style="FONT-SIZE: 11px; VERTICAL-ALIGN: top"&gt;&amp;#x2122;&lt;/sup&gt;&amp;#xA0;Hadoop&lt;sup style="FONT-SIZE: 11px; VERTICAL-ALIGN: top"&gt;&amp;#xAE;&lt;/sup&gt;.
 HDP&amp;#x2019;s architecture enables the combination of computer
 servers with local storage and open source software to create a
 scalable and secure distributed compute and storage platform for
 large data sets. Within the platform, a computing and resource
 management framework called Yet Another Resource Negotiator
 (&amp;#x201C;YARN&amp;#x201D;), orchestrates and enables a centralized
 architecture for batch, interactive and real-time data workloads to
 be executed simultaneously within a comprehensive security,
 governance and operational set of services. HDP integrates with
 existing data center technologies in a way that augments existing
 data center infrastructures, thus enabling more data to be brought
 under management.&lt;/p&gt;

 Hortonworks DataFlow (&amp;#x201C;HDF&amp;#x201D;&lt;sup style="FONT-SIZE: 11px; VERTICAL-ALIGN: top"&gt;&amp;#x2122;&lt;/sup&gt;), is an
 enterprise-scale data ingest and stream processing platform built
 upon open source software, including Apache NiFi. HDF is
 architected to support new data types, such as sensor and machine
 data, server log data, clickstream
 data,&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;geo-location&lt;/font&gt;&amp;#xA0;data
 and social data. These data sets may be captured at the edge of a
 network, including a device such as a point of sale terminal,
 component of machinery or other&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;end-point,&lt;/font&gt;&amp;#xA0;and then
 ingested into HDP. This collected data may then be curated with
 existing data resident within HDP to support full fidelity and
 enable real-time analytic use cases.&lt;/p&gt;

 cloud, at the edge of a network and&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;on-premises.&lt;/font&gt;&amp;#xA0;This
 diversity is driving evolutionary changes for the data platform
 layer. The flexibility of computing resources in the cloud
 supports&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;on-demand&lt;/font&gt;&amp;#xA0;scalability
 and thus, the underlying data management platforms themselves must
 evolve to meet the increasing needs for manageability, security and
 governance. The Hortonworks DataPlane Service (&amp;#x201C;Hortonworks
 DPS&amp;#x201D;&lt;sup style="FONT-SIZE: 11px; VERTICAL-ALIGN: top"&gt;&amp;#x2122;&lt;/sup&gt;), which
 integrates with the Company&amp;#x2019;s HDP and HDF platforms,
 addresses this need by enabling customers to globally manage,
 govern and secure data from multiple sources within this hybrid
 environment. Hortonworks DPS uniquely leverages open source
 technologies like Apache Atlas to accomplish this while also
 creating compatibility with a broad array of data center
 technologies upon which new services and partner applications can
 be built.&lt;/p&gt;

 accrued liabilities. Actual results may differ from these
 estimates.&lt;/p&gt;

 and Other (Topic 350): Simplifying the Test for Goodwill
 Impairment&lt;/i&gt;, which eliminates Step 2 from the goodwill
 impairment test. The standard requires an entity to perform its
 annual, or interim, goodwill impairment test by comparing the fair
 value of a reporting unit with its carrying amount. An entity
 should recognize an impairment charge for the amount by which the
 carrying amount exceeds the reporting unit&amp;#x2019;s fair value. In
 addition, the ASU&amp;#xA0;eliminates the requirements for any
 reporting unit with a zero or negative carrying amount to perform a
 qualitative assessment.&amp;#xA0;The ASU is effective for public

 606)&amp;#xA0;&lt;/i&gt;(the &amp;#x201C;new standard&amp;#x201D;), which
 will replace most existing revenue recognition guidance in U.S.
 GAAP when it becomes effective. The new standard requires an entity
 to recognize the amount of revenue to which it expects to be
 entitled upon transfer of promised goods or services to customers.
 The new standard&amp;#xA0;defines a five-step process in order to
 achieve this core principle, which may require the use of judgment
 and estimates, and also requires expanded qualitative and
 quantitative disclosures relating to the nature, amount, timing and
 uncertainty of revenue and cash flows arising from contracts with
 customers, including significant judgments and estimates used.&lt;/p&gt;

 disclosures. The Company is adopting the new standard as of
 January&amp;#xA0;1, 2018 using the modified retrospective approach. The
 Company&amp;#x2019;s decision was based on a number of factors such as
 the significance of the impact of the new standard on the
 Company&amp;#x2019;s financial results, system readiness, including that
 of software procured from third-party providers, and the
 Company&amp;#x2019;s ability to accumulate and analyze the information

 the new standard on its accounting policies, processes and system
 requirements. The Company has assigned internal resources in
 addition to the engagement of third-party service providers to
 assist in the evaluation and to provide periodic updates to
 management and the Audit Committee. In evaluating the risks
 associated with the adoption of the new accounting standard, the
 Company has identified and scoped the different revenue streams and
 reviewed contracts in each revenue stream for terms and conditions
 that could result in different accounting treatment. Furthermore,
 the Company has made and will continue to make investments in
 systems to enable timely and accurate reporting under the new
 standard. While the Company continues to assess all potential
 impacts under the new standard, significant impacts are expected to
 the timing and amount of support subscription and professional
 services revenue recognized, as well as the capitalization and
 amortization of contract acquisition costs. In addition,
 the&amp;#xA0;Company will&amp;#xA0;update&amp;#xA0;certain disclosures,&amp;#xA0;as
 applicable,&amp;#xA0;included in its filings pursuant to the Securities
 Exchange Act of 1934, as amended, to meet the requirements of the
 new standard.&lt;/p&gt;

 recognition guidance, the Company has concluded it has not
 established vendor-specific objective evidence of fair value
 (&amp;#x201C;VSOE&amp;#x201D;) for support subscriptions and professional
 services offerings in multiple-element arrangements where support
 subscriptions are sold with professional services. The Company
 recognizes revenue on a ratable basis over the period beginning
 when both the support subscription and professional services have
 substantially commenced, and ending at the conclusion of the
 support subscription or professional services period, whichever is
 longer. The new standard, which does not retain the concept of
 VSOE, requires an evaluation of whether support subscriptions and
 professional services are distinct performance obligations, and
 therefore should be separately recognized as the respective
 performance obligations are satisfied based on the standalone
 selling price for each performance obligation, which may not be on
 a ratable basis. Based on the Company&amp;#x2019;s evaluation under the
 new standard, the timing of revenue recognition will change
 significantly for professional services bundled in multiple-element
 arrangements and currently recognized ratably due to lack of VSOE
 for support subscriptions. In particular, professional services
 revenue will be recognized in an earlier period and over a shorter
 timeframe under the new standard as the services are delivered
 compared to the Company&amp;#x2019;s current accounting policy under the
 existing standards and guidance. Also, the timing of recognition
 will change to begin in an earlier period for some support
 subscriptions bundled in multiple-element arrangements compared to
 the Company&amp;#x2019;s current accounting policy for multiple-element
 arrangements whereby recognition generally begins when both the
 support subscription and professional services have substantially
 commenced.&lt;/p&gt;

 has also considered the impact of the guidance in Accounting
 Standards Codification&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;(&amp;#x201C;ASC&amp;#x201D;)&amp;#xA0;340-40&lt;/font&gt;&lt;i&gt;,&lt;/i&gt;&lt;i&gt;&amp;#xA0;Other
 Assets and Deferred Costs; Contracts with Customers&lt;/i&gt;, and the
 interpretations of the FASB TRG for Revenue Recognition from their
 November&amp;#xA0;7, 2016 meeting with respect to the capitalization
 and amortization of incremental costs of obtaining a contract
 (&lt;i&gt;e.g.&lt;/i&gt;, sales commissions). For contracts with an expected
 duration greater than one year, the new standard requires the
 capitalization of incremental costs that the Company incurs to
 obtain a contract with a customer that it would not have incurred
 if the contract had not been obtained, provided the Company expects
 to recover the costs. Such capitalized costs are then to be
 amortized on a systematic basis that is consistent with the
 transfer to the customer of the services to which such costs
 relate, and the amortization period may extend beyond the initial
 contract term if renewal commissions on expected renewals are not
 commensurate with the commission on the initial contract. Under the
 Company&amp;#x2019;s current accounting policy, incremental costs
 incurred to obtain a contract are expensed when incurred. Thus, the
 application of the new standard will result in a significant change
 to the Company&amp;#x2019;s current accounting policy for contract
 acquisition costs, which will result in the Company recognizing the
 expense for contract acquisition costs in a different period, and
 over a longer period, compared to the Company&amp;#x2019;s current
 practice under the existing standards and guidance.&lt;/p&gt;

 use of which was postponed by) tax deductions related to equity
 compensation in excess of compensation recognized for financial
 reporting. The change was applied on a modified retrospective
 basis; no prior periods were restated as a result of this change in
 accounting policy.&lt;/p&gt;

 Approximately $38.4&amp;#xA0;million of federal net operating losses
 and $24.4&amp;#xA0;million of state net operating losses (none of which
 were included in the deferred tax assets recognized in the
 condensed consolidated balance sheet as of December&amp;#xA0;31, 2016)
 have been attributed to tax deduction for stock-based compensation
 expense in excess of the related book expense. Under the new
 standard, these previously unrecognized deferred tax assets were
 recognized on a modified retrospective basis as of January&amp;#xA0;1,
 2017. The U.S. federal and state net operating losses recognized as
 of January&amp;#xA0;1, 2017, as described above, have been offset by a
 valuation allowance. As a result, there
 was&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;no&amp;#xA0;tax-related&amp;#xA0;cumulative-effect&lt;/font&gt;&amp;#xA0;to
 accumulated deficit.&lt;/p&gt;

 estimates the grant date fair value of options using the

 date fair value of RSUs and PSUs that are not market-based using
 the closing market price of the Company&amp;#x2019;s common stock on the
 grant date. The Company estimates the grant date fair value of
 market-based PSUs with&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;pre-established&lt;/font&gt;&amp;#xA0;market
 conditions using the Monte Carlo valuation model. The Company
 estimates fair value of each ESPP purchase at the beginning of the
 offering period using the Black-Scholes option pricing model. The
 respective grant date fair values of stock options, restricted
 stock, RSUs, PSUs and each ESPP purchase are recognized on a
 straight-line basis over the requisite service periods, which
 correspond to the vesting periods.&lt;/p&gt;

 the fair value of the awards as determined using the Black-Scholes
 option pricing model and the closing market price of the

 in value, if any, is recognized in the condensed consolidated
 statements of operations during the period the related services are
 performed.&lt;/p&gt;

 fully vested shares of the Company&amp;#x2019;s common stock upon the
 achievement&amp;#xA0;&lt;font style="WHITE-SPACE: nowrap"&gt;of&amp;#xA0;pre-established&amp;#xA0;performance&lt;/font&gt;&amp;#xA0;objectives.
 For PSUs that are not market-based, stock-based compensation
 expense is recognized when the performance objective is expected to
 be achieved. On a quarterly basis, the Company evaluates the
 performance criteria attainment for these PSUs. The cumulative
 effect on current and prior periods of a change in the estimated
 number of PSUs expected to be earned is recognized as compensation
 expense or as a reduction of previously recognized compensation
 expense in the period of the revised estimate. For market-based
 PSUs, stock-based compensation expense is recognized over a
 &amp;#x201C;derived&amp;#x201D; service period. The derived service period is
 inferred from the Monte Carlo valuation model and may be shorter in
 duration than the performance period for a particular market-based
 PSU award. If the PSU award vests as a result of market performance
 of the Company&amp;#x2019;s common stock prior to the end of the derived
 service period, the compensation expense related to the vested
 award that had not previously been recognized would be recognized
 upon vesting.&lt;/p&gt;

 asset and liability approach. Deferred income tax assets and
 liabilities are computed for differences between the financial
 statement and income tax basis of assets and liabilities that will
 result in taxable or deductible amounts in the future. Such
 deferred income tax asset and liability computations are based on
 enacted tax laws and rates applicable to periods in which the
 differences are expected to affect taxable income. A valuation
 allowance is established, when necessary, for any portion of
 deferred income tax assets where it is considered more likely than
 not that it will not be realized.&lt;/p&gt;

 evaluating and estimating its tax positions and tax benefits, which

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;Each share of common stock is entitled to one vote
 for matters to be voted on by the stockholders of the Company. The
 holders of common stock are also entitled to receive dividends
 whenever declared by the Board of Directors from legally available
 funds. The Company has not paid a dividend since its inception, and
 has no current plans to do so.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;2011 Stock Option and Grant Plan&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;In December 2014, in connection with the closing of
 the Company&amp;#x2019;s IPO, the Hortonworks, Inc. 2011 Stock Option
 and Grant Plan, as amended (the &amp;#x201C;2011 Plan&amp;#x201D;), was
 terminated and shares authorized for issuance under the 2011 Plan
 were canceled (except for those shares reserved for issuance upon
 exercise of outstanding stock options). As of September&amp;#xA0;30,
 2017, options to purchase 4,743,019 shares of common stock were
 outstanding under the 2011 Plan pursuant to their original terms
 and no shares were available for future grant.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 15px"&gt;

 &lt;b&gt;&lt;i&gt;2014 Stock Option and Incentive Plan&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The Hortonworks, Inc. 2014 Stock Option and
 Incentive Plan (the &amp;#x201C;2014 Plan&amp;#x201D;) was adopted by the
 Company&amp;#x2019;s Board of Directors in September 2014. The 2014 Plan
 was approved by the Company&amp;#x2019;s stockholders in November 2014
 and became effective immediately prior to the closing of the
 Company&amp;#x2019;s IPO. All remaining shares available in the 2011
 Plan rolled into the 2014 Plan following the consummation of the
 IPO. An amendment and restatement of the 2014 Plan (the
 &amp;#x201C;Amended 2014 Plan&amp;#x201D;) was approved by the Board of
 Directors in April 2016 and by the Company&amp;#x2019;s stockholders in
 May 2016. The Amended 2014 Plan allows the Compensation Committee
 to make equity-based incentive awards to the Company&amp;#x2019;s full
 or part-time officers, employees, &lt;font style="WHITE-SPACE: nowrap"&gt;non-employee&lt;/font&gt; directors and
 consultants.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;The Company initially reserved 6,000,000 shares of
 the Company&amp;#x2019;s common stock for the issuance of awards under
 the 2014 Plan, plus 923,732 shares of the Company&amp;#x2019;s common
 stock that remained available for issuance under the
 Company&amp;#x2019;s 2011 Plan as of the Company&amp;#x2019;s IPO date. The
 amendment and restatement of the 2014 Plan increased the number of
 shares reserved for issuance under the Amended 2014 Plan by
 7,000,000 shares. The Amended 2014 Plan also provides that the
 number of shares reserved and available for issuance under the plan
 will automatically increase each January&amp;#xA0;1, beginning on
 January&amp;#xA0;1, 2015, by five percent of the outstanding number of
 shares of the Company&amp;#x2019;s common stock on the immediately
 preceding December&amp;#xA0;31 or such lesser number of shares as
 determined by the Company&amp;#x2019;s Compensation Committee. This
 number is subject to adjustment in the event of a stock split,
 stock dividend or other change in the Company&amp;#x2019;s
 capitalization.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;In April, June and July 2015, under the 2014 Plan,
 the Company granted an aggregate of 421,484 PSUs to certain
 executive and senior officers (the &amp;#x201C;Grantees&amp;#x201D;) that
 vest upon (a)&amp;#xA0;the achievement of specified performance targets
 as set by the Compensation Committee and (b)&amp;#xA0;the Grantee
 remaining employed during the respective performance cycles over a
 service period of up to three years, with such service periods
 commencing on July&amp;#xA0;1, 2015. The performance target value for
 each performance cycle is based on an average of the applicable
 internal and external billings amounts for the respective
 performance cycle. The number of PSUs that vest for a given
 performance cycle is based on the Company&amp;#x2019;s achievement of
 actual billings relative to the performance target value.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;In October 2015, under the 2014 Plan, the Company
 granted an aggregate of 266,084 PSUs to the Grantees that vest upon
 (a)&amp;#xA0;the achievement of specified performance targets as set by
 the Compensation Committee and (b)&amp;#xA0;the Grantee remaining
 employed for the duration of the respective &lt;font style="WHITE-SPACE: nowrap"&gt;12-month&lt;/font&gt; performance cycles over a
 service period of up to two years, with such service periods
 commencing on January&amp;#xA0;1, 2016.&amp;#xA0;The number of PSUs that
 vest for a given performance cycle is based on the Company&amp;#x2019;s
 achievement of EBITDA growth and revenue growth relative to the
 linear ranking of a &lt;font style="WHITE-SPACE: nowrap"&gt;pre-selected&lt;/font&gt; group of the
 Company&amp;#x2019;s peers.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;In September 2017, under the Amended 2014 Plan, the
 Company granted 714,711 market-based PSUs to our Chief Executive
 Officer that vest upon (a)&amp;#xA0;the achievement of a specific
 market-based performance goal related to the price of our common
 stock over forty consecutive trading days during a performance
 cycle of four years, with such performance cycle commencing on
 September&amp;#xA0;10, 2017 and (b)&amp;#xA0;the Chief Executive Officer
 remaining employed through achievement of the performance goal. If
 the Company achieves the performance goal within the performance
 cycle, and the Chief Executive Officer remains employed through
 such achievement, 100&amp;#xA0;percent of the PSUs will vest.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;As of September&amp;#xA0;30, 2017, options to purchase
 shares of stock, RSUs and PSUs covering an aggregate of 13,251,586
 shares of common stock were outstanding under the Amended 2014
 Plan.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;On January&amp;#xA0;1, 2017, the shares reserved for
 issuance under the Amended 2014 Plan increased by 3,071,470,
 resulting in 22,579,224 total shares reserved for issuance under
 the Amended 2014 Plan as of September&amp;#xA0;30, 2017, of which
 900,394 shares remained available for issuance.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 9.5pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The Company&amp;#x2019;s ESPP was adopted and approved
 by the Company&amp;#x2019;s Board of Directors in September 2014, was
 adopted and approved by the Company&amp;#x2019;s stockholders in
 November 2014, and was amended in August 2015 to allow employees of
 certain of the Company&amp;#x2019;s &lt;font style="WHITE-SPACE: nowrap"&gt;non-U.S.&lt;/font&gt; subsidiaries to participate
 in the ESPP. The ESPP reserves and authorizes the issuance of up to
 a total of 2,500,000&amp;#xA0;shares of common stock to participating
 employees. The ESPP provides that the number of shares reserved and
 available for issuance will automatically increase each
 January&amp;#xA0;1, beginning on January&amp;#xA0;1, 2015, by the lesser of
 (i)&amp;#xA0;1,000,000 shares of common stock, (ii)&amp;#xA0;one percent of
 the outstanding number of shares of the Company&amp;#x2019;s common
 stock on the immediately preceding December&amp;#xA0;31, or
 (iii)&amp;#xA0;such lesser number of shares as determined by the ESPP
 administrator. This number is subject to adjustment in the event of
 a stock split, stock dividend or other change in the
 Company&amp;#x2019;s capitalization. On January&amp;#xA0;1, 2017, the shares
 reserved for issuance increased by 614,294 resulting in total
 shares reserved for issuance under the ESPP of 4,006,767 as of
 September&amp;#xA0;30, 2017, of which 1,933,343 remained available for
 purchase.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 10px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt" align="justify"&gt;Each employee who is a participant in the ESPP may
 purchase shares by authorizing payroll deductions of up to
 15&amp;#xA0;percent of his or her base compensation during an offering
 period. Unless the participating employee has previously withdrawn
 from the offering, his or her accumulated payroll deductions will
 be used to purchase shares on the last business day of the offering
 period at a price equal to 85&amp;#xA0;percent of the fair market value
 of the shares on the first business day or the last business day of
 the offering period, whichever is lower. Under applicable tax
 rules, an employee may purchase no more than $25,000 worth of
 shares of common stock, valued at the start of the purchase period,
 under the ESPP in any calendar year.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 10pt" align="justify"&gt;As of September&amp;#xA0;30, 2017, there was
 $2.3&amp;#xA0;million of unrecognized stock-based compensation expense
 related to the ESPP, which is expected to be recognized over a
 weighted-average period of 0.58 years.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The 2011 Plan allowed for the granting of options
 that may be exercised before the options have vested. Shares issued
 as a result of early exercise and shares that had not vested are
 deemed to be restricted stock and are subject to a vesting schedule
 identical to the vesting schedule of the related restricted stock
 and options, as well as certain other restrictions. Shares issued
 as a result of early exercise that have not vested are subject to
 repurchase by the Company upon termination of the purchaser&amp;#x2019;s
 employment or services at the price paid by the purchaser, and are
 not deemed to be issued for accounting purposes until those related
 shares vest. The amounts received in exchange for these shares have
 been recorded as a liability on the accompanying condensed
 consolidated balance sheets and will be reclassified into common
 stock and additional &lt;font style="WHITE-SPACE: nowrap"&gt;paid-in&lt;/font&gt; capital as the shares vest.
 The Company&amp;#x2019;s right to repurchase these shares generally
 lapses with respect to 1/48 of the original grant amount per month
 over four years.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 10pt" align="justify"&gt;In February 2016, one of the executives of the
 Company voluntarily canceled a stock option to purchase 1,185,000
 shares. As a result, the Company recognized in general and
 administrative expense a stock-based compensation expense of
 $10.0&amp;#xA0;million during the nine months ended September&amp;#xA0;30,
 2016.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;In July 2011, the Company issued a warrant to
 purchase 6,500,000 shares of Series&amp;#xA0;A preferred stock at an
 exercise price of $0.005 per share. The warrant was issued to
 Yahoo! Inc. (&amp;#x201C;Yahoo!&amp;#x201D;) in connection with the
 Company&amp;#x2019;s Series A financing and the transactions
 contemplated thereby, including commercial agreements with Yahoo!
 providing for support subscription offerings and certain rights to
 technology. As of September&amp;#xA0;30, 2017, the warrant was
 exercisable into 3,250,000 shares of common stock.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 10pt" align="justify"&gt;In June&amp;#xA0;2014, the Company issued to Yahoo!
 a&amp;#xA0;warrant to purchase a number of shares of common stock up to
 one percent of the sum of (i)&amp;#xA0;45,585,496, plus (ii)&amp;#xA0;the
 number of shares of Series&amp;#xA0;D preferred stock or shares of such
 stock issuable upon exercise of warrants to purchase such stock (on
 an as converted to common stock basis) issued or issuable upon
 exercise of warrants to purchase Series&amp;#xA0;D preferred stock that
 were sold, if any, by the Company during the period commencing on
 June&amp;#xA0;9, 2014 and ending immediately prior to the occurrence of
 a&amp;#xA0;corporate event at an exercise price of $8.46&amp;#xA0;per
 share. As of September&amp;#xA0;30, 2017, the warrant was exercisable
 into 476,368 shares of common stock.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 10pt" align="justify"&gt;Each warrant expires nine years from the date of
 issuance. The warrants vested upon consummation of the
 Company&amp;#x2019;s IPO in December 2014. As of September&amp;#xA0;30,
 2017, neither warrant had been exercised into shares of common
 stock.&lt;/p&gt;

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The Company&amp;#x2019;s chief operating decision maker
 reviews financial information on a consolidated basis for the
 purposes of allocating resources and evaluating financial
 performance. The Company&amp;#x2019;s chief operating decision maker has
 direct reports responsible for various functions within the Company
 (&lt;i&gt;e.g.,&lt;/i&gt; business strategy, finance, legal, business
 development, products, etc.) on a consolidated basis. There are no
 segment managers who are held accountable for operations or
 operating results. The Company&amp;#x2019;s primary growth strategy is
 predicated upon the growth of the support subscription business,
 and the Company&amp;#x2019;s key business metrics reflect this strategy.
 Professional services are offered with the overall goal of securing
 and retaining support subscription customers and growing support
 subscription revenue. Accordingly, management has determined the
 Company operates in one reportable segment.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt" align="justify"&gt;The Company has historically presented revenue by
 country, determined by location of sales office. As the Company
 continues to expand its international operations, presenting
 revenue by customer domicile enhances the segment disclosure as it
 is more representative of the Company&amp;#x2019;s geographic
 revenue.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Amended and Restated Revolving Credit Agreement&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;On November 1, 2017, the Company entered into a
 $50.0 million senior secured revolving credit agreement with the
 Bank, documented as an amendment and restatement of its two-year
 senior secured revolving credit facility dated November 2, 2016
 with the Bank (as amended and restated, the &amp;#x201C;Amended and
 Restated Credit Agreement&amp;#x201D;). The proceeds from borrowings
 under the Amended and Restated Credit Agreement, if any, are
 expected to be used for general corporate purposes. Amounts
 outstanding under the Amended and Restated Credit Agreement are
 payable on or before November 1, 2020 and will accrue interest per
 annum at a rate equal to the London Interbank Offered Rate plus
 3.50 percent. Pursuant to the terms of the Amended and Restated
 Credit Agreement, the Company agreed to pay an annual facility fee
 equal to 0.50 percent of the aggregate amount of the revolving
 credit facility commitments and an unused line fee of 0.45 percent
 per annum on the unused commitments. The Amended and Restated
 Credit Agreement contains customary negative covenants and certain
 financial covenants that require the Company to maintain a minimum
 trailing 12-month non-GAAP operating profit and a minimum adjusted
 quick ratio.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 12pt" align="justify"&gt;There are no borrowings outstanding under the
 Amended and Restated Credit Agreement as of the date of this

 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The preparation of condensed consolidated financial
 statements in conformity with U.S. GAAP requires management to make
 estimates and assumptions that affect the reported amounts of
 assets, liabilities, revenue, and expenses, the related disclosure
 of contingent assets and liabilities at the date of the condensed
 consolidated financial statements and the reported amounts of
 expenses during the reporting period. The Company bases its
 estimates and judgments on its historical experience, knowledge of
 current conditions and its beliefs regarding what may occur in the
 future given available information. Estimates, assumptions and
 judgments are used for, but are not limited to, revenue
 recognition, stock-based awards and warrants, accounting for income
 taxes, allowance for doubtful accounts, valuation and determination
 of other-than-temporary impairments of notes receivable and certain
 accrued liabilities. Actual results may differ from these
 estimates.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Changes in Accounting Policies&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The Company adopted ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-09,&lt;/font&gt;
 &lt;i&gt;Compensation-Stock Compensation (Topic 718): Improvements to
 Employee Share-Based Payment Accounting&lt;/i&gt; on January&amp;#xA0;1,
 2017. Under ASU &lt;font style="WHITE-SPACE: nowrap"&gt;No.&amp;#xA0;2016-09,&lt;/font&gt; the Company is
 permitted to make a &lt;font style="WHITE-SPACE: nowrap"&gt;one-time&lt;/font&gt; accounting policy election to
 either account for forfeitures as they occur or to estimate
 forfeitures. The Company elected to account for forfeitures as they
 occur.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;In September 2017, the Company granted
 performance-based restricted stock units (&amp;#x201C;PSUs&amp;#x201D;) that
 have a market-based performance goal related to the price of the
 Company&amp;#x2019;s common stock over forty consecutive trading days
 anytime during a performance period of four years. The market-based
 PSUs are valued using the Monte Carlo valuation model.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0px; FONT-SIZE: 1px; MARGIN-TOP: 8px"&gt;
 &amp;#xA0;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 0pt" align="justify"&gt;The updated stock-based compensation expense and
 income tax accounting policies are as follows:&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 16pt"&gt;
 &lt;i&gt;Stock-Based Compensation Expense&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The Company recognizes compensation costs related
 to employee stock options, time-based restricted stock units
 (&amp;#x201C;RSUs&amp;#x201D;), PSUs and participation in the Company&amp;#x2019;s
 2014 Employee Stock Purchase Plan, as amended (&amp;#x201C;ESPP&amp;#x201D;),
 based on the estimated fair value on the date of grant. The Company
 estimates the grant date fair value of options using the
 Black-Scholes option pricing model. The Company estimates the grant
 date fair value of RSUs and PSUs that are not market-based using
 the closing market price of the Company&amp;#x2019;s common stock on the
 grant date. The Company estimates the grant date fair value of
 market-based PSUs with &lt;font style="WHITE-SPACE: nowrap"&gt;pre-established&lt;/font&gt; market conditions
 using the Monte Carlo valuation model. The Company estimates fair
 value of each ESPP purchase at the beginning of the offering period
 using the Black-Scholes option pricing model. The respective grant
 date fair values of stock options, restricted stock, RSUs, PSUs and
 each ESPP purchase are recognized on a straight-line basis over the
 requisite service periods, which correspond to the vesting
 periods.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;The Company recognizes compensation costs related
 to restricted stock granted in connection with an acquisition based
 upon the fair market value of the underlying shares of common
 stock.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;The Company accounts for stock options and RSUs
 issued &lt;font style="WHITE-SPACE: nowrap"&gt;to&amp;#xA0;non-employees&amp;#xA0;based&lt;/font&gt; on
 the fair value of the awards as determined using the Black-Scholes
 option pricing model and the closing market price of the
 Company&amp;#x2019;s common stock, respectively. The fair value of stock
 options and RSUs granted &lt;font style="WHITE-SPACE: nowrap"&gt;to&amp;#xA0;non-employees&amp;#xA0;are&lt;/font&gt;
 &lt;font style="WHITE-SPACE: nowrap"&gt;re-measured&lt;/font&gt; each period as
 the stock options and RSUs vest, and the resulting change in value,
 if any, is recognized in the condensed consolidated statements of
 operations during the period the related services are
 performed.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;PSUs allow the recipients of such awards to earn
 fully vested shares of the Company&amp;#x2019;s common stock upon the
 achievement &lt;font style="WHITE-SPACE: nowrap"&gt;of&amp;#xA0;pre-established&amp;#xA0;performance&lt;/font&gt;
 objectives. For PSUs that are not market-based, stock-based
 compensation expense is recognized when the performance objective
 is expected to be achieved. On a quarterly basis, the Company
 evaluates the performance criteria attainment for these PSUs. The
 cumulative effect on current and prior periods of a change in the
 estimated number of PSUs expected to be earned is recognized as
 compensation expense or as a reduction of previously recognized
 compensation expense in the period of the revised estimate. For
 market-based PSUs, stock-based compensation expense is recognized
 over a &amp;#x201C;derived&amp;#x201D; service period. The derived service
 period is inferred from the Monte Carlo valuation model and may be
 shorter in duration than the performance period for a particular
 market-based PSU award. If the PSU award vests as a result of
 market performance of the Company&amp;#x2019;s common stock prior to the
 end of the derived service period, the compensation expense related
 to the vested award that had not previously been recognized would
 be recognized upon vesting.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 16pt"&gt;
 &lt;i&gt;Income Taxes&lt;/i&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;The Company accounts for income taxes using an
 asset and liability approach. Deferred income tax assets and
 liabilities are computed for differences between the financial
 statement and income tax basis of assets and liabilities that will
 result in taxable or deductible amounts in the future. Such
 deferred income tax asset and liability computations are based on
 enacted tax laws and rates applicable to periods in which the
 differences are expected to affect taxable income. A valuation
 allowance is established, when necessary, for any portion of
 deferred income tax assets where it is considered more likely than
 not that it will not be realized.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;The tax effects of the Company&amp;#x2019;s income tax
 positions are recognized only if determined &amp;#x201C;more likely than
 not&amp;#x201D; to be sustained based solely on the technical merits as
 of the reporting date. The Company considers many factors when
 evaluating and estimating its tax positions and tax benefits, which
 may require periodic adjustments and which may not accurately
 anticipate actual outcomes.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;The Company accounts for excess tax benefits and
 tax deficiencies as income tax expense or benefit, treated as
 discrete items in the reporting period in which they occur, and
 recognizes previously unrecognized deferred tax assets that arose
 directly from (or the use of which was postponed by) tax deductions
 related to equity compensation in excess of compensation recognized
 for financial reporting.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 8pt" align="justify"&gt;Other than the changes to the Company&amp;#x2019;s
 stock-based compensation expense and income taxes accounting
 policies, there have been no other material changes to the
 Company&amp;#x2019;s significant accounting policies described in the
 Company&amp;#x2019;s Annual Report on Form &lt;font style="WHITE-SPACE: nowrap"&gt;10-K&lt;/font&gt; for the fiscal year ended
 December&amp;#xA0;31, 2016 that have had a material impact on the
 Company&amp;#x2019;s condensed consolidated financial statements and
 related notes.&lt;/p&gt;

 &lt;b&gt;&lt;i&gt;Description of Business&lt;/i&gt;&lt;/b&gt;&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 6pt" align="justify"&gt;Hortonworks, Inc. (the &amp;#x201C;Company&amp;#x201D;) was
 incorporated in Delaware in 2011 and is an industry-leading
 innovator that creates, distributes and supports a new class of
 enterprise data management software solutions built upon open
 source technology. The Company&amp;#x2019;s customers use its
 enterprise-scale data management platforms and services to maximize
 the value of their data by generating business insights and
 supporting their predictive and real-time analytic
 requirements.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 7pt" align="justify"&gt;The Hortonworks Data Platform
 (&amp;#x201C;HDP&amp;#x201D;&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#xAE;&lt;/sup&gt;) is a
 foundational element of the Company&amp;#x2019;s offerings. HDP is an
 enterprise-scale data management platform built upon open source
 software including Apache&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#x2122;&lt;/sup&gt;
 Hadoop&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#xAE;&lt;/sup&gt;. HDP&amp;#x2019;s
 architecture enables the combination of computer servers with local
 storage and open source software to create a scalable and secure
 distributed compute and storage platform for large data sets.
 Within the platform, a computing and resource management framework
 called Yet Another Resource Negotiator (&amp;#x201C;YARN&amp;#x201D;),
 orchestrates and enables a centralized architecture for batch,
 interactive and real-time data workloads to be executed
 simultaneously within a comprehensive security, governance and
 operational set of services. HDP integrates with existing data
 center technologies in a way that augments existing data center
 infrastructures, thus enabling more data to be brought under
 management.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 7pt" align="justify"&gt;The Company&amp;#x2019;s complementary solution,
 Hortonworks DataFlow (&amp;#x201C;HDF&amp;#x201D;&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#x2122;&lt;/sup&gt;), is an
 enterprise-scale data ingest and stream processing platform built
 upon open source software, including Apache NiFi. HDF is
 architected to support new data types, such as sensor and machine
 data, server log data, clickstream data, &lt;font style="WHITE-SPACE: nowrap"&gt;geo-location&lt;/font&gt; data and social data.
 These data sets may be captured at the edge of a network, including
 a device such as a point of sale terminal, component of machinery
 or other &lt;font style="WHITE-SPACE: nowrap"&gt;end-point,&lt;/font&gt; and
 then ingested into HDP. This collected data may then be curated
 with existing data resident within HDP to support full fidelity and
 enable real-time analytic use cases.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 7pt" align="justify"&gt;Today, customers increasingly generate data in the
 cloud, at the edge of a network and &lt;font style="WHITE-SPACE: nowrap"&gt;on-premises.&lt;/font&gt; This diversity is driving
 evolutionary changes for the data platform layer. The flexibility
 of computing resources in the cloud supports &lt;font style="WHITE-SPACE: nowrap"&gt;on-demand&lt;/font&gt; scalability and thus, the
 underlying data management platforms themselves must evolve to meet
 the increasing needs for manageability, security and governance.
 The Hortonworks DataPlane Service (&amp;#x201C;Hortonworks
 DPS&amp;#x201D;&lt;sup style="FONT-SIZE: 85%; VERTICAL-ALIGN: top"&gt;&amp;#x2122;&lt;/sup&gt;), which
 integrates with the Company&amp;#x2019;s HDP and HDF platforms,
 addresses this need by enabling customers to globally manage,
 govern and secure data from multiple sources within this hybrid
 environment. Hortonworks DPS uniquely leverages open source
 technologies like Apache Atlas to accomplish this while also
 creating compatibility with a broad array of data center
 technologies upon which new services and partner applications can
 be built.&lt;/p&gt;
 &lt;p style="MARGIN-BOTTOM: 0pt; FONT-SIZE: 10pt; FONT-FAMILY: Times New Roman; MARGIN-TOP: 7pt" align="justify"&gt;In December 2014, the Company completed its initial
 public offering and concurrent private placement (collectively, the
 &amp;#x201C;IPO&amp;#x201D;). In February 2016, the Company completed a
 &lt;font style="WHITE-SPACE: nowrap"&gt;follow-on&lt;/font&gt; public offering
 of an aggregate of 9,688,750 shares of its common stock, including
 1,263,750 additional shares sold pursuant to the full exercise of
 the option to purchase additional shares by the underwriters, at a
 public offering price of $9.50 per share. Net proceeds to the
 Company were approximately $87.7&amp;#xA0;million after deducting
 underwriting discounts and commissions and offering expenses.&lt;/p&gt;
