>
> When a JobTracker with the {{mapred.jobtracker.restart.recover}} option
> turned on, restarts, it recovers task statuses from all tasks recorded in the
> history for running jobs. Task trackers rejoin the restarted JobTracker and
> report the statuses of the tasks they had last run. These tasks' start time
> is set to 0 in the task reports on the restarted JobTracker. This is as seen
> in the web UI, or from the value of {{TaskReport.startTime}} retrieved from
> the job client.
