--------------------------------------
I tested this patch with TestJobHistory(of HADOOP-4191) and I see that with
this patch, TIP start is added properly.

> JobTracker does not log TIP start information after restart

> In case of JobTracker restart, attempt_0123456789_0001_m_000000_0 might not
> be the first attempt to get scheduled as the attempt id offset changes after
> every restart. For example,
> upon first restart the new attempt id will be
> attempt_0123456789_0001_m_000000_1000. Hence TIP start line never gets logged
> to the job history after the restart, TaskInProgress.isFirstAttempt() always
> returns *false*.
