Brandon Williams commented on CASSANDRA-5102:
---------------------------------------------
Did they show up on the 1.1 side as being down, or not at all?
> upgrading from 1.1.7 to 1.2.0 caused upgraded nodes to only know about other
> 1.2.0 nodes

> 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

> 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.
