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 both nodes.
=46rom the new node I can successfully telnet to ports 7000, 7199 and =
9160 on the seed node (so it's not a connectivity issue - necessary =
ports are open on node firewalls and EC2 security groups).
All nodes have identical cassandra.yaml files, apart from the new node =
has auto-bootstrap set to true.

Despite all this, cassandra still says "No other nodes seen!  Unable to =
bootstrap" when starting on the third node. Any ideas? How can I =
troubleshoot further?

Thanks,

Marcus=
