I am trying to connect titan-1.0.0-hadoop1 with apache-cassandra-3.2.
I am using following " titan-cassandra-myfile.properties ":
storage.cassandra-config-dir=titan-1.0.0- hadoop1/conf/cassandra/cassandra.yaml
storage.backend=cassandra
storage.hostname=localhost
When I use gremlin to execute following command:
g=TitanFactory.open("/path to titan/ titan-1.0.0-hadoop1/conf/titan-cassandra-myfile.properties");
I am getting following error:
java.lang.IllegalArgumentException: Could not instantiate implementation: com.thinkaurelius.titan.diskstorage.cassandra.astyanax.AstyanaxStoreManager at

When I use same configurations with apache-cassandra-1.2.5 and titan-all-0.3.1 , the above config works and it creates a graph.
Please suggest some solution on this , whether is this a compatibility issue or I am doing something wrong.
Thanks, Laxmikant
