Setting up cluster and nodetool ring in 0.8.0
I want to make sure I'm not seeing things from a weird perspective. I have
two Cassandra instances where one is set to be the seed, with autobootstap
disabled and its seed being 127.0.0.1.
The second instance has autobootstrap enabled and the seed IP set to the IP
of the first node.
I start the first node, then the second, with no errors. However, when I
run:
bin/nodetool -h localhost ring
My output shows me only the local machine in my ring. When I run:
bin/nodetool -h localhost join seedNodeIP
It tells me I'm already a part of the ring.
My question is which is correct? I thought, from the documentation, that
both of my nodes would show up in the ring if I ran 'ring' in nodetool.
This is a new cluster.

I might not have set the tokens to 'A' and 'B' respectively, and it didn't
change the results. Of course, if I'm thinking of the token definitions
incorrectly I wouldn't be surprised.

Did you set the token values for you nodes? I remember having similar symptoms when I had a token conflict.

Edward,
I change my seed node to use its route-able IP address as its own seed instead of 127.0.0.1. I still, however, still see the same results when running nodetool.

Do use 127.0.0.1 as a seed (except for single node test clusters) Use a
route-able ip that other cluster nodes can use to reach that node.

Just to close this out, in case anyone was interested... my problem was
firewall related, in that I didn't have my messaging/data port (7000) open
on my seed node. Allowing traffic on this port resolved my issues.

Thanks, Jonathan. Both machines do have the exact same seed list.

Seed lists should _always_ be identical on each machine (which implies
they should _never_ be localhost, in a multinode configuration).
