I have downloaded Titan from the link

[https://github.com/thinkaurelius/titan/wiki/Downloads]

and I started Titan using titan.sh start.

Got this: Forking Cassandra... Running nodetool statusthrift... OK (returned exit status 0 and printed string "running").

Forking Elasticsearch...
Connecting to Elasticsearch (127.0.0.1:9300)..... OK (connected to 127.0.0.1:9300).
Forking Gremlin-Server...
Connecting to Gremlin-Server (127.0.0.1:8182)..... OK (connected to 127.0.0.1:8182).
Run gremlin.sh to connect.

Started gremlin shell using gremlin.sh , gemlin shell has started . But when I ran the below command , i got the below error..

gremlin> graph = TitanFactory.open('conf/titan-cassandra-es.properties')

Hmm, Update 1 says it is from cassandra.log, but you would not be able to find that stack trace in cassandra.log. That is a stack trace from gremlin-server.log. - Jason Plurad

It looks like your Cassandra cluster/node isn't running correctly. I've never used titan.sh but I'd probably look to verify that Cassandra is booting cleanly and staying up.

The message in the log file indicates that the Gremlin Server tried to instantiate a graph configured in conf/gremlin-server/titan-berkeleyje-server.properties. This is probably configured in your gremlin-server.yaml file under graphs->graph.

You already stated in your question that you want to use a graph configured in conf/titan-cassandra-es.properties. So just change that in the gremlin-server.yaml.
