> Key: HADOOP-239
> URL: http://issues.apache.org/jira/browse/HADOOP-239
> Project: Hadoop
> Issue Type: Bug
> Components: mapred
> Reporter: Yoram Arnon
> Assigned To: Sanjay Dahiya
> Priority: Minor
> Attachments: Hadoop-239.patch, Hadoop-239_1.patch

>
> 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.
