Actually, you can debug it after deploying it once. This will require setting some YARN variables to ensure containers are not released even if the application fails. The agent logs report back the commands being invoked and the parameters used to invoke them. Let me try to write that up on the wiki. *I will need a day or so.*
The choice of python was mostly a reflection of going for scripting language that works on Windows and linux. As such it is possible to use any scripting language as long as the agent code is modified to handle various script types. Of course, today the only supported/tested one is python.
