How to change num_tokoens in Cassandra?

Question

I want to change num_tokens value in Cassandra 2.0. But If I do that, I need to delete my existing data. Otherwise it throws an error saying it can't change this configuration.

Is there a way I can do this change without deleting my existing data?

Thanks.

If you want to change the number of virtual nodes on an existing node, you need to rebuild the data on the node. See this.
