---------------------------------
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.
