> The sequence of events is as under :
> # RM is stopped while putting a RMStateStore Event to RMStateStore's
> AsyncDispatcher. This leads to an Interrupted Exception being thrown.
> # As RM is being stopped, RMStateStore's AsyncDispatcher is also stopped. On
> {{serviceStop}}, we will check if all events have been drained and wait for
> event queue to drain(as RM State Store dispatcher is configured for queue to
> drain on stop).
> # This condition never becomes true and AsyncDispatcher keeps on waiting
> incessantly for dispatcher event queue to drain till JVM exits.
> *Initial exception while posting RM State store event to queue*
