> When map-reduce jobs are finished, the metrics corresponding to their counters are not
cleaned up.  This is a memory leak, but worse it means that an ever-increasing amount of metric
data is sent to the metrics system (if one is enabled).
> The fix is for JobInProgress to clean up the metrics it created when the job is complete.
