I found the am container log, like below. Here we know error happened in
pipeline, maybe some dn error. And I also found some other reason which close
the JobHistoryEventHandler. So MR AM can't write the information for JH. So
client counldn't know whether the appplication is finished.

This problem is serious , especially for hive. Job must rerun meaninglessly!
So I think we need to retry the operation of writing history event.
