------------------------------------
Ravi actually found this while testing HADOOP-4191.
> Finish time of a TIP is incorrectly logged to the jobhistory upon jobtracker
> restart

> Key: HADOOP-5278
> URL: https://issues.apache.org/jira/browse/HADOOP-5278
> Project: Hadoop Core
> Issue Type: Bug
> Components: mapred
> Reporter: Amar Kamat
>
> Upon recovery, the jobtracker replays the attempt information to the JIP.
> Upon seeing the attempt-end info, the JIP _completes_ the TIP (which sets the
> finish time to current time) and logs it to the new jobhistory file (the
> _.recover_ file). After seeing the task(tip) finish line, the recovery
> manager changes the finish time to correct finish time but the new jobhistory
> file still contains the wrong value for the finish time seen while completing
> the TIP.
