Subject [jira] [Created] (MAPREDUCE-4480) T_ATTEMPT_KILLED after SUCCEEDED can happen for reduces too
Date Wed, 25 Jul 2012 18:00:46 GMT
Robert Joseph Evans created MAPREDUCE-4480:
----------------------------------------------

             Summary: T_ATTEMPT_KILLED after SUCCEEDED can happen for reduces too 
                 Key: MAPREDUCE-4480
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4480
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 3.0.0, 2.2.0-alpha
            Reporter: Robert Joseph Evans
            Priority: Critical


This does not seem to impact 0.23.  If speculative execution is enabled then a T_ATTEMPT_KILLED
event can come in after the task has transitioned to SUCCEEDED.  This causes the MapRetroactiveKilledTransition
to kill the Job, because it expects to only handle map tasks.
