Subject [jira] [Commented] (YARN-2459) RM crashes if App gets rejected for any reason and HA is enabled
Date Thu, 28 Aug 2014 20:57:12 GMT

Jian He commented on YARN-2459:
-------------------------------

 Mayank, thanks for working on the issue.  The current change saves the initial state, but
doesn't store the final state and diagnostics of the app. And RM will retry this app if not
saving the final state.  I think we should do the following as New_saving state is handling
it.
{code}
.addTransition(RMAppState.NEW, RMAppState.FINAL_SAVING,
       RMAppEventType.APP_REJECTED,
       new FinalSavingTransition(new AppRejectedTransition(),
           RMAppState.FAILED))
{code}

> If RM HA is enabled and used Zookeeper store for RM State Store.
> If for any reason Any app gets rejected and directly goes to NEW to FAILED
> then final transition makes that to RMApps and Completed Apps memory structure but that
doesn't make it to State store.
> Now when RMApps default limit reaches it starts deleting apps from memory and store.
In that case it try to delete this app from store and fails which causes RM to crash.
> Thanks,
> Mayank
