             Summary: Server should refuse to start if authentication is 'required' but no auth method is configured
                 Key: KUDU-1941
                 URL: https://issues.apache.org/jira/browse/KUDU-1941
             Project: Kudu
          Issue Type: Bug
          Components: rpc, security
    Affects Versions: 1.3.0
            Reporter: Todd Lipcon


I started a server with --rpc_authentication=required, but didn't specify a keytab. The server started, but when I try to connect to it, the server abruptly disconnects the client (so the client gets a network error and retries). The server spews the log:
{code}
0316 08:16:36.271464 (+    39us) negotiation.cc:281] Negotiation complete: Invalid argument: Server connection negotiation failed: server connection from 127.0.0.1:55920: RPC authentication (--rpc_authentication) may not be required unless Kerberos (--keytab_file) or external PKI (--rpc_certificate_file et al) are configured
{code}
