Brandon Williams commented on CASSANDRA-4120:
---------------------------------------------

One last thing; if we could indicate up/down status in the list like 'ring' that could be very helpful, since when confronted with a list of IPs it can be a useful indicator of which node you're actually looking for.  Otherwise, +1.

> 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._
