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.
