Subject [jira] Commented: (CASSANDRA-1678) describe_schema_versions does not list downed hosts
Date Fri, 29 Oct 2010 19:17:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12926412#action_12926412
] 

Gary Dusbabek commented on CASSANDRA-1678:
------------------------------------------

the 'missing hosts' Jonathan referred to were the live hosts that did not respond to the version
query.  There could be other missing hosts that getLiveMembers() didn't return because they
were down.

Would it suit everybody if we included the unreachable members at version=DD.INITIAL_VERSION?
