Subject [jira] Commented: (CASSANDRA-665) Persist token ring across cluster restarts
Date Mon, 04 Jan 2010 19:33:55 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-665?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12796309#action_12796309
] 

Jonathan Ellis commented on CASSANDRA-665:
------------------------------------------

So a node would add a UUID applicationState that it gossips, and if another node sees that
UUID coming from a different IP, it can replace the old IP with the new one in TokenMetadata
etc.  (I think we want to keep using IP addresses internally for e.g. MessagingService rather
than doing an extra lookup on each message send.)

> This prevents users from shooting their foot by shutting down a cluster, then restarting
it with a subset of the former nodes.
