Subject [jira] [Commented] (YARN-4957) Add getNewReservation in ApplicationClientProtocol
Date Thu, 19 May 2016 00:42:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-4957?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15290194#comment-15290194
] 

Carlo Curino commented on YARN-4957:
------------------------------------

[~seanpo03] thanks for addressing my comments right away. I agree on keeping things aligned
with application API, and I am happy with the rest of your answers (including the justification
of test failures).  
Please open a JIRA for the refactoring of test cases (agreed is beyond the scope of this patch,
but we should keep track of this). 

I will wait for jenkins to do its thing to double check checkstyle and javadocs, and then
proceed to commit.

> Currently submitReservation returns a ReservationId if sucessful. This JIRA propose adding
a getNewReservation in ApplicationClientProtocol for the following reasons:
>   * Prevent zombie reservations in the face of client and/or network failures post submitReservation
>   * Align reservation submission with application submission
