Eric Evans commented on CASSANDRA-4120:
---------------------------------------
bq. Throw them away, I would say, since we've done this before when upgrading
majors.
OK, https://github.com/acunu/cassandra/commit/f7864d and
https://github.com/acunu/cassandra/commit/397644 should cover that (patch
output reflects these changes as well).
bq. No. After the big removetoken rewrite, you couldn't removetoken in a mixed
0.8.2/0.8.3 cluster, so this isn't a big deal, as long as we document it in
NEWS.

> Gossip identifies hosts by UUID
> -------------------------------
>
> Key: CASSANDRA-4120
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4120
> Project: Cassandra
> Issue Type: Sub-task
> Components: Core
> Reporter: Sam Overton
> Assignee: Eric Evans
> Labels: virtualnodes, vnodes
>
> Since there is no longer a one-to-one mapping of host to token, a UUID should
> be used to identify a host. This impacts:
> * Gossip
> * Hinted Hand-off
> * some JMX operations (eg. assassinateEndpointUnsafe)
> _Edit: Identify host by UUID, not IP_
> _Edit: Added table of patch links._
