[jira] [Created] (MAPREDUCE-2960) A single TT disk failure can cause the job to fail

A single TT disk failure can cause the job to fail
--------------------------------------------------

                 Key: MAPREDUCE-2960
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2960
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
          Components: tasktracker
    Affects Versions: 0.20.204.0
            Reporter: Eli Collins
             Fix For: 0.20.205.0


TaskInProgress#kill in the JT fails because TaskStatus#setFinishTimes fails because no start time was set. There's no start time because TaskTracker#run (DefaultTaskController#initializeJob) failed before it was set. The fix is to have TT#launchTask set the start time before it starts the task runner, this way there's a valid start time even if TT#run fails.
