--------------------------------------------

This info should be logged, so that it is durable in the face of jobtracker restarts too

> job tracker WI drops jobs after 24 hours

>          URL: http://issues.apache.org/jira/browse/HADOOP-239
>      Project: Hadoop
>         Type: Bug

>   Components: mapred
>     Reporter: Yoram Arnon
>     Priority: Minor

>
> 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).
