You do not need a restart if you use nodetool refresh

Otherwise a rolling restart will do the trick.

Thanks that's very helpful.  I'm assuming there's no requirement to stop or restart Cassandra?

Thanks,

Renaming a CF is not directly supported. 

You can:
1) Add the new CF using the CLI or CQL
2) On each node copy the SSTable files and use the new CF name. 
3) Drop the old CF using the CLI or CQL
4) The Drop CF command will create a snapshot, you may want to delete this. 

Hope that helps.

How can I rename a column family (if version matters, I'm interested in both 0.8.x and 1.0.x).

Thanks,
