Description
Currently, Tajo's protobuf-based RPC protocol is not very portable since it is a custom implementation for the RPC stubs generated by protobuf.
Recently, Google has open-sourced GRPC (http://grpc.io), an RPC framework for protobuf. Using GRPC for Tajo's RPC implementation will improve the portability of the protocol due to GRPC's support for many languages, including Java, C++, and even C#.
