Helena Edelson commented on SPARK-2593:
---------------------------------------

Here is a good example of just one of the issues: it is difficult to locate a 
remote spark actor to publish data to the stream. Here I have to have the 
streaming actor get created and in the preStart, publish a custom message with 
`self`which my actors in my ActorSystem can receive in order to get the 
ActorRef to send to. This is incredibly clunky.

I will try to carve out some time to do this PR this week.
