> 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.
