Not really.  Many of the batches are empty RDDs, and the scheduler delay is still in the range of seconds.  This only happen after a few hours of running the application.  Everything works initially.

> Scheduler Delay (in UI Advanced Metrics) for a task gradually increases from 5 ms to 30+ seconds in a Spark Streaming application, where multiple Kafka direct streams are processed.  These kafka streams are processed separately (not combined via union).  
> It causes the task processing time to increase greatly and eventually stops working.
