Titan unable to connect to Cassandra

enter image description here

I'm trying to code to connect Tital to this Cassandra with this code:

    TitanGraph graph = TitanFactory.build()
            .set("storage.backend","cassandra")
            .set("storage.hostname","127.0.0.1")
            .open();

However, I am getting this error:
