----------------------------------------

[~saint....@gmail.com] One more question, I can see those method from 
Admin.proto has higher priority. But what is the criteria to decide what kind 
of methods should go to Admin.proto vs Client.proto. It seems all of them are 
implemented at RSRpcService.java any ways. 

> add Ping into HBase server for deprecated GetProtocolVersion

> Our HBase service is hosted in AWS. We saw cases where the connection between 
> the client (Asynchbase in our case) and server stop working but did not throw 
> any exception, therefore traffic stuck. So we added a "Ping" feature in 
> AsyncHBase 1.5 by utilizing the GetProtocolVersion() API provided at RS side, 
> if no traffic for given time, we send the "Ping", if no response back for 
> "Ping", we assume the connect is bad and reconnect. 
> Now we are upgrading cluster from 94 to 1.2. However, GetProtocolVersion() is 
> deprecated. To be able to support same detect/reconnect feature, we added 
> Ping() in our internal HBase 1.2 branch, and also patched accordingly in 
> Asynchbase 1.7.
> We would like to open source this feature since it is useful for use case in 
> AWS environment.
