[jira] [Commented] (YARN-5349)
TestWorkPreservingRMRestart#testUAMRecoveryOnRMWorkPreservingRestart fail
intermittently
[ 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?
