Hi [~apurtell] [~vjasani], 

{quote}
It also seems likely that changes were made to downstream classes like 
ServerRpcConnection expecting NettyRpcServer's particulars without updating 
SimpleServerRpcConnection and/or SimpleRpcServer
{quote}

Looks like SimpleRpcServer is completely broken in 2.5. That's a bit 
concerning. We have seen some cases of direct memory leaks apparently related 
to NettyRpcServer among our customers running deployments based out of 2.2. In 
such cases, our immediate workaround in the absence of a code fix is to switch 
to SimpleRpcServer.  And we still have the aforementioned HBASE-26708 open. How 
confident are we with current state of NettyRpcServer in 2.5?

Also, compatibility wise, would it be ok to remove it entirely on a minor 
release?
