Please check the logs of the JanusGraph Server instance. It probably produced an error when starting which should tell you what the problem is. If you paste that log here (possibly redacted), then we can maybe help you find the root problem

The problem here is that JanusGraph Server tries to connect to Elasticsearch, but this fails. Because of that, JanusGraph cannot open the graph and therefore not bind a graph traversal source g which leads to the error you're seeing when you try to execute a traversal.

Here is the relevant part of the server logs:

7959 [main] WARN org.janusgraph.diskstorage.es.rest.RestElasticSearchClient - Unable to determine Elasticsearch server version. Default to SEVEN.

java.net.ConnectException: Connection refused

What I'm wondering however is this:

7999 [main] WARN org.apache.tinkerpop.gremlin.server.GremlinServer - Graph [graph] configured at [conf/janusgraph-cql-lucene.properties] could not be instantiated and will not be available in Gremlin Server. GraphFactory message: GraphFactory could not instantiate this Graph implementation [class org.janusgraph.core.JanusGraphFactory]

So your config file for JanusGraph is named conf/janusgraph-cql-lucene.properties which indicates that you want to use Lucene instead of Elasticsearch as the index backend? Is that correct? Or is the name of this config file just wrong/misleading?

If you want to use Elasticsearch, then you need to inspect your config in that .properties file regarding Elasticsearch and check why JanusGraph cannot connect to Elasticsearch.

If you don't want to use Elasticsearch, then you have probably started JanusGraph previously with a different config that included Elasticsearch as the index backend. The relevant config option here is index.search.backend which has the mutability level GLOBAL_OFFLINE. This means that JanusGraph stores its config value in its storage backend (CQL in your case) and it will ignore any changes made after that to the config file for this option.
If this is the problem, then you can either use the management API to change this global option or maybe just start with a fresh database if you don't already have important data in the database (assuming that you're still in the set-up phase).

How to configure JanusGraph for Lucene as the index backend is described here. You basically just need these entries in your .properties file:

index.search.backend=lucene
index.search.directory=/data/searchindex

But as I've said in my earlier comment, you apparently did already start JanusGraph with a configuration for Elasticsearch. You now either need to change that config (most importantly index.search.backend) as described here or remove all stored data in Cassandra and initialize JanusGraph from a fresh start.

It's however a bit unusual to use Lucene together with Cassandra as Cassandra is a scalable storage backend whereas Lucene only works for a single-instance JanusGraph deployment. So, if you want to be able to scale JanusGraph, then Lucene isn't a good choice. Elasticsearch or Solr would be better choices in that case.
