JobTracker does not clean up task entries at job completion
-----------------------------------------------------------
Key: HADOOP-740
URL: http://issues.apache.org/jira/browse/HADOOP-740
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.8.0
Reporter: Owen O'Malley
Assigned To: Owen O'Malley
The JobTracker never calls removeTaskEntry on tasks that don't fail. This
causes the JobTracker to use more and more heap space as jobs run. The fix is
to:
removeTaskEntry on reduces in completeTask
removeTaskEntry on everything when a job is killed or completes
