    Description

      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.
