Hi All,
I have a spark streaming + kafka program written by Scala, it works
well on Spark 1.3.1, but after I migrate my Spark cluster to 1.4.1 and rerun
this program, I meet below exception:
ERROR scheduler.ReceiverTracker: Deregistered receiver for stream

I did some web searching, and tried to add zkclient-0.3 jar in the
classpath, but still get same issue, Who can share your experience on solving
this issue? thanks in advance.
