All of the nodes are 0.8.x and no longer 0.7.2 ? It is peculiar. As

each node could help. I've had issues in the past with JMX --
thinking I had configured it for IP x.x.x.x and went crazy only to see
that it was never
Thanks for all your helpful suggestions - I've now got it working. It was down
to a combination of things.
1. A missing rule in a security group
2. A missing DNS name for the new node, so its default name was defaulting to
localhost
3. Google DNS caching the failed DNS lookup for the full

Hi,
First time here. I'm having trouble adding a third node to an existing 2-node
ring (successfully upgraded from 0.72) running cassandra 0.8rc1 (successfully
upgraded from 0.72) on ubuntu on EC2.
Evidently the seed node is working as the second node is already talking to it,
nodetool lists
What region and availability zones are the different nodes in? Are you using
EC2 Snitch? Did you set up the cluster using the Datastax AMI?

Check the listen_address and rpc_address in the yaml file for each node. I
think they are normally set to the private and public respectively.
This may make your live easier
