-----------------------------------------

             Summary: flushTimer in JobHistoryEventHandler should purge canceled flushTimerTask
                 Key: MAPREDUCE-6617
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6617
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 3.0.0
            Reporter: Kousuke Saruta

In JobHistoryEventHandler, flushTask is not purged after it's canceled so GC never sweep flushTask.
It can cause memory leak.
