Thomas Jungblut commented on HAMA-358:
--------------------------------------

I asked myself if we need to strictly stick with RPC for BSP Communication.
What about just setting up a SequenceFile and sending it across the network using plain old streams?

We can later add asynchronous communication during computational phases if the SequenceFile reached it's blocksize...

What do you think of it?

> The goal of this project is performance evaluation of RPC frameworks (e.g., Hadoop RPC, Thrift, Google Protobuf, ..., etc) to figure out which is the best solution for Hama BSP communication. Currently Hama is using Hadoop RPC to communicate and transfer messages between BSP workers.
