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

             Summary: NonAggregatingLogHandler can throw RejectedExecutionException
                 Key: MAPREDUCE-5623
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5623
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Tsuyoshi OZAWA
            Assignee: Tsuyoshi OZAWA


This problem is caused by handling APPLICATION_FINISHED events after calling sched.shotdown()
in NonAggregatingLongHandler#serviceStop().

org.apache.hadoop.mapred.TestJobCleanup can fail because of RejectedExecutionException by
NonAggregatingLogHandler.
