Jason Lowe resolved MAPREDUCE-4982.
-----------------------------------

    Resolution: Duplicate

This is fixed by the changes in MAPREDUCE-4893.  That has since been pulled into branch-0.23,
so closing this as a duplicate.

> Saw a job that hung with one pending map task that never ran.  The task was in the SCHEDULED
state with a single attempt that was in the UNASSIGNED state.  The AM looked like it was waiting
for a container from the RM, but the RM was never granting it the one container it needed.
> I suspect the AM botched the container request bookkeeping somehow.  More details to
follow.
