Jian He commented on MAPREDUCE-5397:
------------------------------------
My impression on this issue was I submitted a job, the first few attempts(2 or
3) of the job all failed because of the above reason. Eventually the last
attempt got passed. But after I made a clean build and re-deploy the cluster,
I couldn't reproduce anymore. Feel free to reopen this if necessary, and also
share some logs. tx
