[jira] Updated: (MAPREDUCE-1410) Task-Cleanup attempt cannot be given KillTaskAction if the main attempt is killed with a KillTaskAction

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1410?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Priyo Mustafi updated MAPREDUCE-1410:
-------------------------------------

    Attachment: MAPREDUCE-1410.patch

Existing patch wasn't valid anymore because 1) JobTracker.jobs don't hold completed job in memory any longer. 
2) Code was trying to contact namenode.  Added MiniDFSCluster.

The changes are only to Junit's and the original code fix remains as is in the patch

> If the main attempt is killed with a KillTaskAction and is added to tasksReportedClosed, then the cleanup-attempt for the task (with same id) can not be given a KillTaskAction, since tasksReportedClosed already contains the attemptID.  
> The attemptID should be removed from  tasksReportedClosed in incompleteSubTask() method.
