This jira will track the various improvements that will be done in the JobHistory component of Hadoop. The main goals:
1) Make the content format friendly for consumption by other apps
2) Improve the management of the history files.
3) Be able to completely rely on the JobHistory files for anything to do with getting the status of completed jobs, both at the JobClient end, and at the web-UI end
