> This is a subtask of [HAMA-975|https://issues.apache.org/jira/browse/HAMA-975].
> Since 4.0.16, Netty provides the native socket transport for Linux using JNI.
> This transport has advantages as below. 
> - higher performance
> - produces less garbage
> - edge-triggered
> - supports TCP-CORK
> So Hama will have better performance in async fashion communication. 
> Full description for this can be found in [Netty Wiki|http://netty.io/wiki/native-transports.html]
