--------------------------------------
[~boryas] is this still a pending task? SAMZA-1349 looks like a duplicate ?
> Run stop() in the StreamProcessor in the same thread as other events.

> stop() should be running in the same thread as other events. Since sometimes
> it is invoked form the container thread, it may end up running at the same
> time as another event from ZK.
> Even, if one of the first things stop() does is stopping the scheduler, an
> event still may be running. So the solution would be to call the stop () from
> JobCoordinator, using the same debouncing thread as every other event. It
> will do the following:
> * Cancel all the currently en-queued tasks. It still may have one task
> running.
> * Schedule itself (stop()) on the same debounce thread.
> Note. Since we are using scheduler's thread to run stop(), we won't be able
> to run scheduler.stop(). But that should be fine, since it is a daemon
> thread.
