Haibo Chen created MAPREDUCE-6771: ------------------------------------- Summary: Diagnostics information is lost in .jhist if task containers are killed by Node Manager. Key: MAPREDUCE-6771 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6771 Project: Hadoop Map/Reduce Issue Type: Bug Components: mrv2 Affects Versions: 2.7.3 Reporter: Haibo Chen Assignee: Haibo Chen
Task containers can go over their resource limit, and killed by Node Manager. Then MR AM gets notified of the container status and diagnostics information through its heartbeat with RM. However, it is possible that the diagnostics information never gets into .jhist file, so when the job completes, the diagnostics information associated with the failed task attempts is empty. This makes it hard for users to root cause job failures that are often caused by memory leak. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
