Error when running cassandra-stress on Centos 6.7

Question

I am trying to build a 3 node Cassandra cluster on Centos 6.7. I had no issues installing it and I can successfully run the cqlshell commands. However whenever I try to run the stress test as very simple testing case as:

cassandra-stress write n=10

I get this error

java.lang.RuntimeException: com.datastax.driver.core.exceptions.NoHostAvailableException: All host(s) tried for query failed (tried: localhost/127.0.0.1:9042 (com.datastax.driver.core.exceptions.TransportException: [localhost/127.0.0.1] Cannot connect))

        ... 6 more

Both the seeds, listen_address and rpc_address have the correct addresses and I opened 9042, 7000, 7001 and 7199 ports in the firewall. So I am not entirely sure what might be the problem.

what does nodetool status come back with? Cassandra-stress is looking at your localhost. — apesa

run nodetool status

Take one of the printed IP addresses and try: cassandra-stress write n=10 -node <ip address>
