Brandon Williams commented on CASSANDRA-4347:
---------------------------------------------
Yes, a pre-assassinate capture is what we need. The old IPs showing in the
LEFT state is assassinate working (and they do appear cross-cluster)
> IP change of node requires assassinate to really remove old IP

> Key: CASSANDRA-4347
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4347
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 1.0.10
> Environment: RHEL6, 64bit
> Reporter: Karl Mueller
> Assignee: Brandon Williams
> Priority: Minor
> Attachments: dev-cass-post-assassinate-gossipinfo.txt

> In changing the IP addresses of nodes one-by-one, the node successfully moves
> itself and its token. Everything works properly.
> However, the node which had its IP changed (but NOT other nodes in the ring)
> continues to have some type of state associated with the old IP and produces
> log messages like this:
