    Description

      Concerns about SimpleRpcServer are not new, and not new to 2.5.  @chenxu noticed a problem on HBASE-23917 back in 2020. After some simple evaluations it seems quite broken.

      When I run an async version of ITLCC against a 2.5.0 cluster configured with hbase.rpc.server.impl=SimpleRpcServer, the client almost immediately stalls because there are too many in flight requests. The logic to pause with too many in flight requests is my own. That's not important. Looking at the server logs it is apparent that SimpleRpcServer is quite broken. Handlers suffer frequent protobuf parse errors and do not properly return responses to the client. This is what stalls my test client. Rather quickly all available request slots are full of requests that will have to time out on the client side.

      Exceptions have three patterns but they all have in common SimpleServerRpcConnection#process. It seems likely the root cause is mismatched expectations or bugs in connection buffer handling in SimpleRpcServer/SimpleServerRpcConnection versus downstream classes that process and parse the buffers. It also seems likely that changes were made to downstream classes like ServerRpcConnection expecting NettyRpcServer's particulars without updating SimpleServerRpcConnection and/or SimpleRpcServer. That said, this is just a superficial analysis.
