nemon lou updated MAPREDUCE-5155:
---------------------------------
Description:
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.
