> Key: HADOOP-787
> URL: https://issues.apache.org/jira/browse/HADOOP-787
> Project: Hadoop
> Issue Type: Bug
> Components: mapred
> Affects Versions: 0.9.0
> Reporter: Owen O'Malley
> Assigned To: Arun C Murthy
>
> The job tracker currently runs out of memory when a user runs a lot of small
> jobs back to back. To bound the amount of RAM that the job tracker consumes
> recording completed/failed jobs, I think that the JobTracker should limit the
> number of "remembered" jobs per a user to
> jobtracker.max.remembered.task.per.user (default 100).
