Hi Gerard, first, thanks for your explanations regarding the jar files!

So the closure as a function is serialized, sent across the wire, deserialized there, and *still* you need the class files? (I am not sure I understand what is actually sent over the network then. Does that serialization only contain the values that I close over?) If I understand correctly what you are saying, then the documentation at https://people.apache.org/~pwendell/catalyst-docs/running-on-mesos.html (list item 8) needs to be extended quite a bit, right? Thanks Tobias
