Tianying Chang updated HBASE-17453:
-----------------------------------
Description:
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.

We used GetProtocolVersion in AsyncHBase to detect unhealthy connection to RS
since in AWS, sometimes it enters a state the connection
