You need to edit the cassandra.yaml file.
I vaguely remember changing the rpc_address to 0.0.0.0. Or you can try setting it to the IP address of the YCSB client which you are using.

you will need to look at your logs on the cassandra side to see what shows up there. this sounds like a firewall issue.

Closing as stale. Please attempt to use the new CQL bindings and open an issue if you have problems.
