> StreamingContext.start() can throw exception because 
> DStream.validateAtStart() fails (say, checkpoint directory not set for 
> StateDStream). But by then JobScheduler, JobGenerator, and ReceiverTracker 
> has already started, along with their actors. But those cannot be shutdown 
> because the only way to do that is call StreamingContext.stop() which cannot 
> be called as the context has not been marked as ACTIVE.
