[jira] [Created] (MAPREDUCE-3986) TaskAttemptCompletionEvent not being sent for task attempts that were killed after a sibling attempt succeeds

TaskAttemptCompletionEvent not being sent for task attempts that were killed after a sibling attempt succeeds
-------------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-3986
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3986
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.23.0
            Reporter: Bikas Saha
            Assignee: Bikas Saha
             Fix For: 0.23.2


When TaskImpl transitions to SUCCEEDED then it kills the other running task attempts. In the SUCCEEDED state the TaskImpl state machine ignores T_ATTEMPT_KILLED events from those killed attempts. Hence those completions events are not reported to the job. Every other attempt completion event is reported to the job.
