Michael Kjellman commented on CASSANDRA-5102:
---------------------------------------------
at this point i just went ahead and upgraded all the nodes (was more worried
about getting the cluster back up)
I do notice though that the 1.2.0 nodes show net_version of 6.
as nodes were upgraded to 1.2.0 they didn't show up in the ring on the 1.1.7
side anymore.
gossipinfo on 1.2.0 nodes (ubuntu 12.04) look like:

> Key: CASSANDRA-5102
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5102
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.2.0
> Reporter: Michael Kjellman
> Assignee: Brandon Williams
> Priority: Blocker
>
> I upgraded as I have since 0.86 and things didn't go very smoothly.
> I did a nodetool drain to my 1.1.7 node and changed my puppet config to use
> the new merged config. When it came back up (without any errors in the log) a
> nodetool ring only showed itself. I upgraded another node and sure enough now
> nodetool ring showed two nodes.
> I tried resetting the local schema. The upgraded node happily grabbed the
> schema again but still only 1.2 nodes were visible in the ring to any
> upgraded nodes.
> "Interesting" Log Lines:

> WARN 23:04:03,361 No host ID found, created
> 5cef7f51-688d-46c3-9fe4-6c82bde4bb98 (Note: This should happen exa
> ctly once per node).
