>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>    Affects Versions: 2.5.0
>            Reporter: Jason Lowe
>            Assignee: Eric Payne

> Occasionally the MapReduce AM can "get stuck" trying to shut down.  MAPREDUCE-6049 and
MAPREDUCE-5888 were specific instances that have been fixed, but this can also occur with
uber jobs if the task code inadvertently leaves non-daemon threads lingering.
> We should explicitly shutdown the JVM after the MapReduce AM has unregistered and all
services have been stopped.
