Subject [jira] [Commented] (CASSANDRA-4561) update column family fails
Date Mon, 27 Aug 2012 21:15:08 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13442726#comment-13442726
] 

Pavel Yaskevich commented on CASSANDRA-4561:
--------------------------------------------

if you still have such timestamps and messages that CF already exists means that schema wasn't
empty on restart and was reloaded from one of the nodes. I'm currently working on the patch
which would fix timestamp situation on node's start up.
