@jongyoul I think there's 2 follow up things to do.
* Unify the communication frame between zeppelin server & interpreter
process.
* Change the pull mode to push mode so that interpreter process can push
data to zeppelin-server.
When we consider to choose netty or thrift, we need to consider these 2
things.
