> There was a case where the JobTracker lost track of a set of tasks that were on a task
tracker. It appears to be a race condition because the ExpireTrackers thread doesn't lock
the JobTracker while updating the state. The fix would be to build a list of dead task trackers
and then lock the job tracker while updating their status.
