It looks pretty close to RMI to me. Right now, one can put Maps, Lists, Integers, arrays, etc, in a response and have it serialized how they want (JSON, XML, etc). If we went the HadoopRPC way, we would need to make everything we used implement Writeable AFAIK. Regardless of what ends up happening, I think the communication/RPC mechanism should be at the same level it is now for requests - that should keep things loosely coupled and make it easy to add/change communication mechanisms in the future if desired. -Yonik
