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

             Summary: SimpleRpcServer is broken and should be removed
                 Key: HBASE-27097
                 URL: https://issues.apache.org/jira/browse/HBASE-27097
             Project: HBase
          Issue Type: Bug
          Components: rpc
    Affects Versions: 2.5.0
            Reporter: Andrew Kyle Purtell


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 and I am not sure anyone is interested in it enough to 
attempt a fix. In my opinion it is not suitable for release in its current 
state and should be removed from 2.5.0 and up. 

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 exceptions to the client. 

Exceptions have three patterns

1) "Protocol message end-group tag did not match expected tag"
