> We have seen some situations where maps are still running when all the
> reducers have completed. This could happen because of lost TT's, interplay of
> speculative tasks with bad TT's etc. If the maps take a long time to run, it
> unnecessarily delays the job completion time, as this map output is not
> required anyways. The JT should possibly kill running maps when all the
> reducers have completed.
