I think you may have a data centre defined in the strategy_options for the keyspace that does not have any nodes in it. Check the dc names in the create keyspace statement match the names in your cassandra-topology.propeties file (assuming you are using the PropertyFileSnitch), or that you have nodes assigned to all dc's.
Hope that helps. ----------------- Aaron Morton Freelance Cassandra Developer @aaronmorton http://www.thelastpickle.com On 13 May 2011, at 13:45, Anurag Gujral wrote: > Hi All, > I run following command on one of my nodes to move the token > from 0 to 2. > /usr/cassandra/cassandra/bin/nodetool -h 10.170.195.204 -p 8080 move 2.
