> I had a bunch of TaskTrackers time out because they were in the middle of job
> cleanup and the JobTracker restarted them by responding to emitHeartbeat with
> UNKNOWN_TASKTRACKER. Afterwards, I ended up with both the new and the
> restarted TaskTrackers on the list:
> node1100_1234, 0-10 seconds since heartbeat
> node1100_4321, >10,000 seconds since heartbeat
