> 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).
