Subject [jira] [Commented] (YARN-2545) RMApp should transit to FAILED when AM calls finishApplicationMaster with FAILED
Date Tue, 30 Sep 2014 11:01:33 GMT

    [ https://issues.apache.org/jira/browse/YARN-2545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14153065#comment-14153065

Tsuyoshi OZAWA commented on YARN-2545:
--------------------------------------

Thanks for your reporting, [~zhiguohong]. I think we should fix to report the states of app
correctly. How about changing to check the state of apps and dispatch RMAppEventType#ATTEMPT_FAILED
in RMAppAttemptImpl#AMUnregisteredTransition?

> If AM calls finishApplicationMaster with getFinalApplicationStatus()==FAILED, and then
exits, the corresponding RMApp and RMAppAttempt transit to state FINISHED.
> I think this is wrong and confusing. On RM WebUI, this application is displayed as "State=FINISHED,
FinalStatus=FAILED", and is counted as "Apps Completed", not as "Apps Failed".
