LinuxTaskController throws NPE when task fails to start
-------------------------------------------------------

                 Key: MAPREDUCE-2233
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2233
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: task-controller
    Affects Versions: 0.22.0, 0.23.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
         Attachments: mapreduce-2233.txt

When the LinuxTaskController is incorrectly configured (eg wrong permissions or path) an NPE is thrown when it tries to kill the failed tasks, since there is no known pid.
