Subject [jira] [Created] (YARN-2196) Add Application duplicate APP_ACCEPTED events can be prevented with a flag
Date Mon, 23 Jun 2014 21:48:26 GMT
Anubhav Dhoot created YARN-2196:
-----------------------------------

             Summary: Add Application duplicate APP_ACCEPTED events can be prevented with
a flag 
                 Key: YARN-2196
                 URL: https://issues.apache.org/jira/browse/YARN-2196
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.4.0
            Reporter: Anubhav Dhoot


YARN-1365 adds a flag to AddApplicationAttemptSchedulerEvent that prevents a duplicate ATTEMPT_ADDED
event  in recovery. We can do something similar to AddApplicationSchedulerEvent to avoid the
following transition.
{code}
// ACCECPTED state can once again receive APP_ACCEPTED event, because on
    // recovery the app returns ACCEPTED state and the app once again go
    // through the scheduler and triggers one more APP_ACCEPTED event at
    // ACCEPTED state.
    .addTransition(RMAppState.ACCEPTED, RMAppState.ACCEPTED,
        RMAppEventType.APP_ACCEPTED)
{code}
