Subject [jira] [Created] (HDFS-10685) libhdfs++: return explicit error when non-secured client connects to secured server

Bob Hansen created HDFS-10685:
---------------------------------

             Summary: libhdfs++: return explicit error when non-secured client connects to
secured server
                 Key: HDFS-10685
                 URL: https://issues.apache.org/jira/browse/HDFS-10685
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Bob Hansen


When a non-secured client tries to connect to a secured server, the first indication is an
error from RpcConnection::HandleRpcRespose complaining about "RPC response with Unknown call
id -33".

We should insert code in HandleRpcResponse to detect if the unknown call id == RpcEngine::kCallIdSasl
and return an informative error that you have an unsecured client connecting to a secured
server.
