Subject [jira] [Commented] (CASSANDRA-5032) Downed node loses its host-id
Date Thu, 06 Dec 2012 00:58:58 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5032?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13510992#comment-13510992
] 

Brandon Williams commented on CASSANDRA-5032:
---------------------------------------------

I tested it and it works, but yeah, you'll have to wipe out the system table, or I think starting
once with -Dcassandra.load_ring=false will work.

on restart of those.
