Gremlin Console Issue

[atul161]

Hi ,

I have a docker compose file setup.
After opening shell of janus graph server when i go to gremlin console and try to
define schema then error occurs.
I have cassandra connected as a backend which is protected by id and password.
Any Help will be appreciated.

graph = JanusGraphFactory.open("conf/janusgraph-cql-server.properties")

gives error and even i am not able to print schema.

Did you try and exec into the Cassandra container and login to Cassandra with cqlsh and the cassandra/cassandra credentials? That would be the first thing to check.
