Subject Re: Unsuccessful attempt to add a second node to a ring.
Date Wed, 01 Aug 2012 09:51:58 GMT
Hi Roshni,
no they are the same, my changes in cassandra.yaml were only in the
listen_address, rpc_address, seeds and initial_token field.
The rest is exactly the same as on node1.

That's how the file looks on node2:
