Subject [jira] [Commented] (CASSANDRA-2963) Add a convenient way to reset a node's schema
Date Wed, 25 Jan 2012 09:12:44 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13192946#comment-13192946
] 

Pavel Yaskevich commented on CASSANDRA-2963:
--------------------------------------------

Now when CASSANDRA-1391 is committed, to reset the schema you will just need to truncate schema_{keyspaces,
columnfamilies, columns} and re-set Schema.instance to initial (blank) state.

> People often encounter a schema disagreement where just one node is out of sync.  To
get it back in sync, they shutdown the node, move the Schema* and Migration* files out of
the system ks, and then start it back up.  Rather than go through this process, it would be
nice if you could just tell the node to reset its schema.
