Since JIRA doesn't let us mark this as a subtask of a different JIRA project, I think it's best to mark it as related and leave it for tracking the MapReduce-specific changes. Alternate suggestions for tracking the MR-specific changes related to YARN-1336? > ShuffleHandler should handle NM restarts > ---------------------------------------- > > Key: MAPREDUCE-5652 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5652 > Project: Hadoop Map/Reduce > Issue Type: Bug > Affects Versions: 2.2.0 > Reporter: Karthik Kambatla > Assignee: Jason Lowe > Labels: shuffle > > ShuffleHandler should work across NM restarts and not require re-running map-tasks. On NM restart, the map outputs are cleaned up requiring re-execution of map tasks and should be avoided. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
