--------------------------------

I found that the function ContainerExecutor.getRunCommand() in the trunk patch
is different from that in branch-2/branch-0.23 patch. Is there any reason why
we are doing that ?
> allow OS scheduling priority of NM to be different than the containers it
> launches

> It would be nice if we could have the nodemanager run at a different OS
> scheduling priority than the containers so that you can still communicate
> with the nodemanager if the containers out of control.
> On linux we could launch the nodemanager at a higher priority, but then all
> the containers it launches would also be at that higher priority, so we need
> a way for the container executor to launch them at a lower priority.
> I'm not sure how this applies to windows if at all.
