> I run into this once: testFetchFailureWithRecovery(org.apache.hadoop.mapreduce.v2.app.TestFetchFailure): Num completion events not correct expected:<1> but was:<0>
> There is a race condition between job.getTaskAttemptCompletionEvents and dealing with JOB_TASK_ATTEMPT_COMPLETED event.
> If job.getTaskAttemptCompletionEvents invoked because of task in SUCCEEDED state ,but before JOB_TASK_ATTEMPT_COMPLETED event scheduled,the test case will fail.
