    A good piece of work!. I like that there is a much better test coverage for the Yarn cluster
now.
    
    @rmetzger Can you comment on a few open questions? 
    
     - There are two projects for yarn: "flink-yarn" and "flink-yarn-tests". Can we combine
them in one project? The reason why we put the tests in "flink-scala" into a different project
was only beause the Scala macros uses in "flink-scala" caused problems otherwise. Since the
Yarn project is not using macros, I see no reason for the separation.
     
     - The example for the YARN session should probably not refer to a local file ("file:///...")
     
     - There is a bit of a strange mechanism in computing the ports for the application master
(base port plus attempt-id or so). Can this be simplified? Also, what happens if that port
is already in use, per chance?
       
     - How hard would it be to make the client parameter that starts a yarn session for the
job simpler? Something like `-y` rather than `-m yarn-cluser`?
