Subject [jira] [Commented] (YARN-5057) resourcemanager.security.TestDelegationTokenRenewer fails in trunk
Date Mon, 03 Oct 2016 07:19:20 GMT

    [ https://issues.apache.org/jira/browse/YARN-5057?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15541747#comment-15541747
] 

Naganarasimha G R commented on YARN-5057:
-----------------------------------------

Thanks for the patch [~jlowe], encountered the same stack trace in YARN-4855 too. And seems
like approach taken in the patch makes sense to me we wait for 10 seconds in a loop which
is checking in a interval of 10 ms and throws the exception, though later in the test case
we try to assert the same. 
So overall LGTM and +1 , if not further comments will commit it.
