Subject [jira] [Resolved] (CASSANDRA-4805) live update compaction strategy destroy counter column family
Date Tue, 16 Oct 2012 01:27:03 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-4805?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Ellis resolved CASSANDRA-4805.
---------------------------------------

    Resolution: Invalid

Don't update CQL3 columnfamilies from the cli, it will rip out the column definitions as you
see here.  (1.2 prevents this, in 1.1 we are leaving it as-is.)
