Ah. Another thing. I haven't looked at your code to see if it's handled,
but akka requires executors to open a listening socket, all the related files
(such as the trust store) also need to somehow be sent to the executors... it
would kinda suck to force everybody to copy the files manually to all possible
places where executors may run.
In Yarn mode that should be easy (using the distributed cache), but no idea
whether that's easy or even possible in standalone or mesos...
