Wrongly configured 'hadoop.job.history.user.location' can cause jobs to be pinned in JobTracker's memory forever ----------------------------------------------------------------------------------------------------------------
Key: MAPREDUCE-1598 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1598 Project: Hadoop Map/Reduce Issue Type: Bug Components: jobtracker Affects Versions: 0.21.0 Reporter: Amar Kamat Priority: Blocker Wrongly configured 'hadoop.job.history.user.location' can disable job-history. Jobs retires when JobHistory notifies the JobTracker after moving the history file to the done folder (i.e mapreduce.jobtracker.jobhistory.completed.location). If the JobHistory gets disabled, JobTracker would not receive any notification and thus jobs will be pinned in JobTracker's memory forever. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
