> In CoarseGrainedExecutorBackend, we subscribe DisassociatedEvent in executor backend actor and exit the program upon receive such event...
> let's consider the following case
> The user may develop an Akka-based program which starts the actor with Spark's actor system and communicate with an external actor system (e.g. an Akka-based receiver in spark streaming which communicates with an external system)  If the external actor system fails or disassociates with the actor within spark's system with purpose, we may receive DisassociatedEvent and the executor is restarted.
> This is not the expected behavior.....
