How to change the tokens?

I am trying to change the token of the Cassandra node but it is using a saved token. I have tried "-Dcassandra.load_ring_state=false" in the startup script but did not find it useful. Any thoughts?

Thanks,SC

Not sure why you would need to do that...And regardless you will need to move the data to change the tokens.

You need to move the node to the new token you would like. Take care to only do one move operation at a time in the ring and also do a repair –pr and cleanup after the move operation.

See nodetool move for more information
