" Krb5Authenticator runs inside Gremlin Server and authenticates users of gremlin clients (e.g. Gremlin Console). " this is configured as part of gremlin-server.yaml. 
When I run just "graph" alone  from gremlin-console, I get error "Authenticator is not ready to handle requests".
Whereas when I run JanusGraphFactory it passes. Not sure why do we get this. My current service keytab had 2 principals and I configured one. Will it create problem?
