Subject [jira] [Commented] (YARN-6409) RM does not blacklist node for AM launch failures
Date Mon, 15 May 2017 20:22:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-6409?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16011261#comment-16011261
] 

Robert Kanter commented on YARN-6409:
-------------------------------------

The overall approach seems fine to me, but the {{TestRMAppAttemptTransitions}} failure looks
related and doesn't fail without the patch.  Can you take a look at it?  Looks like you need
to check {{instanceof}} before casting.  Also, on the depth of 3 thing, is there a reason
the {{SocketTimeoutException}} won't be at the same depth each time?

> Currently, node blacklisting upon AM failures only handles failures that happen after
AM container is launched (see RMAppAttemptImpl.shouldCountTowardsNodeBlacklisting()).  However,
AM launch can also fail if the NM, where the AM container is allocated, goes unresponsive.
 Because it is not handled, scheduler may continue to allocate AM containers on that same
NM for the following app attempts.
