Thanks Devaraj for your comments. Done the validation of history files obtained from TestLostTracker,
TestJobTrackerRestart, TestJobTrackerRestartWithLostTracker and identified issues in history
files HADOOP-5272, HADOOP-5276, HADOOP-5278, HADOOP-5282. Thanks Amar for fixing these new
issues fast. Testcase is also modified.

Attaching patch after incorporating code changes based on Devaraj's & Amar's comments.

> Changes in job history might break the history parser which in turn might break some
features like jobtracker-recovery, history-viewer etc. There should be a testcase that catches
these incompatible changes early and informs about the expected change.
