Ravi Gummadi commented on HADOOP-4191:
--------------------------------------

1 & 2.  Local file system seems to be good enough.

3. Will add validation of format of SPLITS and TOTAL_MAPS, TOTAL_REDUCES, FINISHED_MAPS, FINISHED_REDUCES, FAILED_MAPS, FAILED_REDUCES.

4. Will do validation of all keys, values of history file by comparing them with actual values obtained from JT.

> 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.
