> add Ping into HBase server for deprecated GetProtocolVersion
> ------------------------------------------------------------

> Project: HBase
> Issue Type: Improvement
> Components: regionserver
> Affects Versions: 1.2.2
> Reporter: Tianying Chang

> 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.
