Thomas Jungblut commented on HAMA-565:
--------------------------------------
I would also be interested in it. But Hama is just transferring plain binary,
so if you catch a whole message to another peer, you could get the raw data
back with a bit of reverse engineering.
A very simplistic approach would be to try a telnet on the RPC communication
port of a peer and look at the results, or sniffing the stuff with tcpdump.

> Network traffic among the peers in the cloud is currently done without any

> I just came across a compression codec for Hadoop making it possible to
