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:

Have you set the
Data, commitlog, saved cache directories to different ones in each yaml file for each node?

Subject: Unsuccessful attempt to add a second node to a ring.

Hi Everybody!

I'm trying to add a second node to an already operating one node cluster.

Some specs:
- cassandra 1.0.7
- both nodes have a routable listen_address and rpc_address.
- Ports are open: (from node2) telnet node1 7000 is successful
- Seeds parameter on node2 points to node 1.

[node1] nodetool -h localhost ring
Address         DC          Rack        Status State   Load            Owns    Token
node1.ip     datacenter1 rack1       Up     Normal  74.33 KB        100.00% 0

- initial token on node2 was specified

I see something like that in the logs on node2:

DEBUG [main] 2012-07-31 13:50:38,640 CollationController.java (line 76) collectTimeOrderedData
 INFO [main] 2012-07-31 13:50:38,641 StorageService.java (line 667) JOINING: waiting for ring and schema information

 INFO [main] 2012-07-31 13:51:08,642 StorageService.java (line 667) JOINING: getting bootstrap token

DEBUG [main] 2012-07-31 13:51:08,645 Table.java (line 387) applying mutation of row 4c

but it doesn't join the ring:

[node2] nodetool -h localhost ring
Address         DC          Rack        Status State   Load            Owns    Token
node2.ip   datacenter1 rack1       Up     Normal  13.49 KB        100.00% 85070591730234615865843651857942052864

I'm attaching the full log from node2 startup in debug mode.

When I didn't specified the initial token on node2 I ended up with exception like that:
"Exception encountered during startup: No other nodes seen!  Unable to bootstrap.If you intended to start a single-node cluster, you should make sure your broadcast_address (or listen_address) is listed as a seed.
Otherwise, you need to determine why the seed being contacted has no knowledge of the rest of the cluster.  Usually, this can be solved by giving all nodes the same seed list."

I'm not sure how to proceed now. I found a couple of posts with problems like that but they weren't very useful.
