Subject Re: Changing a cluster name

First, make sure that you call nodetool flush after modifying the system
table.  That's probably why it's not surviving the restart.

Second, I believe you will have to do this across all nodes and restart
them at the same time.  Otherwise, cluster name mismatches will prevent the
nodes from communicating with each other.
