Robert Joseph Evans commented on MAPREDUCE-4372:
------------------------------------------------
The patch looks good, I have one minor comment.
I would prefer to see
{code}
(ShutdownHookManager.get().isShutdownInProgress()) == false
{code}
as
{code}
!ShutdownHookManager.get().isShutdownInProgress()
{code}
The javadoc warnings appear to be cause by MAPREDUCE-4355
