TaskTracker Decommission that waits for all map(intermediate) outputs to be pulled -----------------------------------------------------------------------------------
Key: MAPREDUCE-2291 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2291 Project: Hadoop Map/Reduce Issue Type: Improvement Components: jobtracker Reporter: Koji Noguchi On our clusters, users were getting affected when ops were decommissioning a large number of TaskTracker nodes. Correct me if I'm wrong, but current decommission of TaskTrackers only waits for the running tasks to finish but not the jobs where map outputs are kept on that decommissioning tasktrackers. Any ways we can handle this better? -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira
