Duo Zhang commented on HBASE-16433:
-----------------------------------
On a mobile phone so reply all things here, include the questions on RB.
The parameter type in protobuf stub is the actual type of request and in the
general call method it is Message, so this means we can not find the error at
compile time. And for the RpcController, I do not think the 'possible null' is
a problem if the upper layer need it to receive something. For exapmle, I think
we will always have a pcrc when doing scan because we need it to get the
CellScanner, otherwise the logic is broken. For AsyncTable implementation, you
always need a pcrc to check if we are in error.

> AsyncRpcChannel can not be used by protobuf stub. We should implement the
> async logic along with the RpcChannel interface of protobuf.
