Jonathan Ellis commented on CASSANDRA-872:
------------------------------------------
This is a place where trying to automate too much can very well make things
worse. Shutting nodes off automatically -- which is what leaving gossip
amounts to -- is very dangerous.
Again, the problem here is one that is readily discovered and easily corrected.
Logging a warning is a good improvement and completely free of unanticipated
side effects. :)

> URL: https://issues.apache.org/jira/browse/CASSANDRA-872
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Affects Versions: 0.6
> Reporter: Stu Hood
> Fix For: 0.7
>
>
> Currently, multiple nodes can join the ring with the same token (particularly
> when people copy the data directory between machines). The symptom is that
> the new endpoint joins the ring successfully, but both nodes can only see
> themselves in the ring (according to nodetool).
> Instead of this behaviour, we would want gossip to die rather than joining
> with a duped token.
