Agreement (collectively, the “Shares”). 
 WHEREAS, as a condition and inducement for Cloudera to enter into the Merger
Agreement, Stockholder and Cloudera are entering into this Agreement. 
 NOW, THEREFORE, the parties hereto hereby agree as follows: 

1. Agreement to Vote Shares. 

(a) Until the Expiration Date, at the Hortonworks Stockholder Meeting and at every other stockholder meeting of Hortonworks called to consider
the Hortonworks Voting Proposal, and at every postponement or adjournment thereof, and on every action proposed to be approved by written consent of Hortonworks Stockholders with respect to any of the following, Stockholder shall vote all

Shares and New Shares are capable of being voted: 
 (i) in favor of the adoption of the Merger Agreement and any proposal to adjourn or
postpone any meeting of the stockholders of Hortonworks at which the adoption of the Merger Agreement is submitted for the consideration and vote of the stockholders of Hortonworks to a later date if there are not proxies representing a sufficient
number of shares of Hortonworks Common Stock to approve such matters on the date on which the meeting is held; 
 (ii) against any
Acquisition Proposal made by any Person (other than Cloudera) and any Acquisition Transaction proposed by any Person (other than Cloudera); and 

 (iii) against any other action, agreement or transaction involving Hortonworks or any of
the Hortonworks Subsidiaries that is intended, or would reasonably be expected, to impede, interfere with, delay, postpone, adversely affect or prevent the consummation of the Merger or the other transactions contemplated by the Merger Agreement.

 (b) Prior to the Expiration Date, Stockholder shall not enter into any agreement or understanding with any person to vote or give
instructions in any manner inconsistent with this Section 2. 
 (c) Notwithstanding anything to the contrary set
forth herein, nothing in this Agreement shall prohibit or otherwise impair the right or ability of Stockholder to exercise his or her fiduciary duties in his or her capacity as a director or officer of Hortonworks, including by voting in his or her
capacity as a director to effect a Hortonworks Board Recommendation Change, in each case, in accordance with the terms of the Merger Agreement. 

2. Transfer and Encumbrance. Stockholder agrees, during the period beginning on the date hereof and ending on the Expiration Date (as
defined below), not to sell, transfer, exchange, pledge or otherwise dispose of or encumber (collectively, “Transfer”) any Shares or any New Shares, in each case without the prior written consent of Cloudera; provided, that
nothing contained herein shall prohibit (a) the net settlement of Stockholder’s options to purchase shares of Hortonworks Common Stock (to pay the exercise price thereof and any tax withholding obligations), (b) the net settlement of
Stockholder’s restricted stock units (including performance-based restricted stock units) settled in shares of Hortonworks Common Stock (to pay any tax withholding obligations), (c) the exercise of Stockholder’s options to purchase shares
of Hortonworks Common Stock, to the extent such options would expire prior to the Effective Time, (d) the exercise of Stockholder’s options to purchase shares of Hortonworks Common Stock or the receipt upon settlement of Stockholder’s
restricted stock units, and the sale of a sufficient number of such shares of Hortonworks Common Stock acquired upon exercise of such options or settlement of such restricted stock units as would generate sales proceeds sufficient to pay the
aggregate applicable exercise price of shares then exercised under such options and the taxes payable by Stockholder as a result of such exercise or settlement, (e) such Stockholder from selling Shares under any written plan providing for the
trading of Shares in accordance with Rule 10b5-1 under the Exchange Act (a “10b5-1 Plan”) that is described on the signature page hereto or which is put
in place after the date hereof in order to replace an expired or expiring 10b5-1 Plan (provided, that any such 10b5-1 Plan shall be implemented in accordance with
the requirements of Hortonworks’ insider trading policy and on substantially consistent terms as the expired or expiring 10b5-1 Plan, except as may be required to implement additional sales pursuant to
the foregoing clause (d)), (f) any Transfer where such Stockholder retains sole direct and indirect voting control over such Shares or New Shares through the term of this Agreement, (g) any Transfer to an Affiliate of Stockholder, or

the extent required by any non-consensual legal order, by divorce decree or by will, intestacy or other similar law; provided, however, that in the case of the foregoing
clauses (g) or (h)(i), any such Transfer shall only be permitted if and to the extent that the transferee of such Shares or New Shares agrees to be bound by and subject to the terms and provisions hereof to the same effect as the
transferring Stockholder. Stockholder acknowledges that the intent of the foregoing sentence is to ensure that the Shares and any New Shares are voted in accordance with the terms hereof. 

3. No Participation in Litigation. Stockholder hereby agrees not to commence or participate in, and use reasonable best efforts to, if
requested by Cloudera, take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Cloudera, Merger Sub, Hortonworks or any of their respective successors relating to the

respect to which Stockholder otherwise acquires beneficial ownership after the date of this Agreement and prior to the Expiration Date, including, without limitation, shares issued or issuable upon the conversion, exercise or exchange, as the case
may be, of all securities held by Stockholder that are convertible into, or exercisable or exchangeable for, shares of Hortonworks Common Stock (“New Shares”), shall be subject to the terms and conditions of this Agreement to the
same extent as if they constituted Shares.
