Eric Evans commented on CASSANDRA-4120: --------------------------------------- See the description above for a table with patch links. I have no doubt that more work will be needed here, but I wanted to get these up and solicit feedback; Some questions that remain to be answered are: * On an upgrading node, what do we do with old hints that were stored by token? * During an upgrade, on already upgraded node, what do we do with hints meant for a yet-to-be-upgraded node? * Do we support the use of removeToken (now removeNode) on partially upgraded clusters? > 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._ > h3.
