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.
> Add a convenient way to reset a node's schema

> 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.
