> Priority: Minor

> There are three hacks while create Python API for Streaming (https://github.com/apache/spark/pull/2538) :
> 1. daemonize the callback server thread, by 'thread.daemon = True' before start it https://github.com/bartdag/py4j/issues/147
> 2. let callback server bind to random port, then update the Java callback client with real port. https://github.com/bartdag/py4j/issues/148
> 3. start the callback server later. https://github.com/bartdag/py4j/issues/149
> These hacks should be removed after py4j has fix these issues.
