Description

The jobtracker's WI, keeps track of jobs executed in the past 24 hours.
if the cluster was idle for a day (say Sunday) it drops all its history.
Monday morning, the page is empty.
Better would be to store a fixed number of jobs (say 10 each of succeeded and failed jobs).

Also, if the job tracker is restarted, it loses all its history.
The history should be persistent, withstanding restarts and upgrades.
