One thing to add is that the same application will not have this issue when 
there is only one stream, even this one stream has a much higher load.  The 
issue seems to have something to do with multiple streams.

> 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.
