Do i need restart or format the data on the cluster after I change the token. If not, what should I do to rebalance the cluster?
If I need format the cluster after I change the token?(3 posts) (2 voices)
You can only change a node's token by issuing it a 'move' command. You can do this from the command line using the nodetool utility or graphically with OpsCenter:
By issuing a move command the token for the node will change and the node will fetch/send the data from/to other nodes in the cluster. Additionally OpsCenter can 'rebalance' your entire cluster by issuing a series of moves. For more info on how that works internally see:
Got it, thanks a lot
