Hey Anupam, I think Jim is asking about building non-MR application masters using the RM/NM. I think Arun has promised to post a design doc soon. In the meantime, I'm just reading through the code and fixing little issues I come across (e.g., https://issues.apache.org/jira/browse/MAPREDUCE-2630 and https://issues.apache.org/jira/browse/MAPREDUCE-2633).
Jim, what sort of app are you looking to build? I'd be happy to have some company wading through the code.
