Thomas Jungblut commented on HAMA-742:
--------------------------------------
Personally, I think the best solution would be to use RPC for our distributed
system communication. And use a plain netty with Selectors (epoll) for our
messaging system. RPC has too much overhead for message imho.

> To solve HDFS 2.0 compatibility issue, we have to change a lot of codes for
> Hadoop 2.0 RPC, moreover, yarn RPC doesn't support asynchronous call directly.
> Ultimately, we can pursue the performance and integrate more easily with
> hadoop multi-versions by having our own RPC.
