Subject [jira] [Created] (YARN-5802) Application priority updates add pending apps to running ordering policy
Date Sat, 29 Oct 2016 20:17:59 GMT
Bibin A Chundatt created YARN-5802:
--------------------------------------

             Summary: Application priority updates add pending apps to running ordering policy
                 Key: YARN-5802
                 URL: https://issues.apache.org/jira/browse/YARN-5802
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bibin A Chundatt
            Assignee: Bibin A Chundatt
            Priority: Critical


{{LeafQueue#updateApplicationPriority}}
{code}
 getOrderingPolicy().removeSchedulableEntity(attempt);

      // Update new priority in SchedulerApplication
      attempt.setPriority(newAppPriority);

      getOrderingPolicy().addSchedulableEntity(attempt);
{code}
We should add again to ordering policy only when  attempt available in first case.Else during
application attempt removal will try to iterate on killed application still available in pending
Ordering policy.Which can cause RM to crash.
