Subject [jira] [Commented] (YARN-5349) TestWorkPreservingRMRestart#testUAMRecoveryOnRMWorkPreservingRestart fail intermittently
Date Mon, 31 Jul 2017 17:56:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-5349?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16107689#comment-16107689
] 

Jason Lowe commented on YARN-5349:
----------------------------------

Ran into this on branch-2.8 recently.  Looks like the unit test, and other unit tests in this
suite, make the assumption that containers will never be allocated in the response to the
first allocate call.  That's an incorrect assumption.  It also assumes that all of the containers
requested will arrive in the same response which is also incorrect.

[~sandflee] are you still planning on posting a patch for this?
