When you add a new node, cassandra will pick the node that has the most data then split its token. In this case the data distribution among all nodes become uneven. What's the right strategy/steps to rebalance the node load after adding new nodes? Here's one example: I have a cluster of node A, B, C, D. Now I want to add E and F, after adding the nodes, the data distribution will change from 1/1/1/1 to 1/1/0.5/0.5/0.5/0.5, is this correct?

Thanks,
