--------------------------------------

I tested this patch with HADOOP-4191 and I see that correct value of finish time of task(tip) is logged to history file with this patch.

> 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.
