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

Yes, I was planning on adding a test case if I can get some time to do so.

> We've seen a number of cases where the history server is showing the wrong task as the
reason a job failed.  For example, "Task task_1383802699973_515536_m_027135 failed 1 times"
when some other task had failed 4 times and was the real reason the job failed.
