JobTracker holds stale references to retired jobs via speculated tips ----------------------------------------------------------------------
Key: MAPREDUCE-1316 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1316 Project: Hadoop Map/Reduce Issue Type: Bug Components: jobtracker Reporter: Amar Kamat JobTracker fails to remove speculative tasks' mapping from _taskToTIPMap_ if the job finishes and retires before the tracker (running the speculative tasks) reports back. In such cases a stale reference is held to TaskInProgress (and thus JobInProgress) long after the job is gone leading to memory leak. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
