>
> The stop method in the NodeManager gets called twice when the NodeManager is
> shut down via the shutdown hook.
> The first is the stop that gets called directly by the shutdown hook. The
> second occurs when the NodeStatusUpdaterImpl is stopped. The NodeManager
> responds to the NodeStatusUpdaterImpl stop stateChanged event by stopping
> itself. This is so that NodeStatusUpdaterImpl can notify the NodeManager to
> stop, by stopping itself in response to a request from the ResourceManager
> This could be avoided if the NodeStatusUpdaterImpl were to stop the
> NodeManager by calling its stop method directly.
