Apache Cassandra™ 1.2

Commands and options

Warning: Using the shuffle utility on a running production system is not advised. It may take hours or even days to complete!

Bootstrapping a new data center is a much safer way to enable vnodes. Use the procedure described in Enabling virtual nodes on an existing production cluster instead.
