[jira] [Commented] (YARN-2545) RMApp should transit to FAILED when AM calls finishApplicationMaster with FAILED

    [ https://issues.apache.org/jira/browse/YARN-2545?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14638610#comment-14638610 ] 

Hong Zhiguo commented on YARN-2545:
-----------------------------------

RMAppEventType#ATTEMPT_FAILED is not suitable because it leads to check of "maxAppAttempt". 
Here AM unregistered with "getFinalApplicationStatus()==FAILED",  the RMApp should transit to "FAILED" without check of "maxAppAttempt"

In current implementation of RMAppImpl, targetedFinalState of FinalSavingTransition is statically determined by (preState, eventType). A simple solution is to replace ATTEMPT_UNREGISTERED event with 2 types of event: ATTEMPT_UNREGISTERED_SUCC and ATTEMPT_UNREGISTERED_FAIL.

Any suggestion?

> 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".
