[jira] [Created] (MAPREDUCE-2761) New TaskController code doesn't run on Windows

New TaskController code doesn't run on Windows
----------------------------------------------

                 Key: MAPREDUCE-2761
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2761
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: task-controller, tasktracker
    Affects Versions: 0.20.204.0, 0.23.0
            Reporter: Todd Lipcon


After MAPREDUCE-2178, TaskController assumes that pids are always available. The shell executor object that's used to launch a JVM isn't retained, but rather the pid is set when the task heartbeats. On Windows, there are no pids, and since the ShellCommandExecutor object is no longer around, we can't call process.destroy(). So, the TaskController doesn't work on Cygwin anymore.
