Subject Re: Getting Cassandra 0.7 beta2 to work - creating keyspaces
Date Sun, 10 Oct 2010 21:29:22 GMT
Since 0.7 beta 2 or something, locators have differents names.
In conf/cassandra.yaml :
Out of the box, Cassandra provides
#     * org.apache.cassandra.locator.SimpleStrategy
#     * org.apache.cassandra.locator.NetworkTopologyStrategy
#     * org.apache.cassandra.locator.OldNetworkTopologyStrategy

Good luck
