>
> Rebalancing in FULL_AUTO mode will relentlessly (though mostly greedily) seek
> a balance in both partitions and states across nodes with minimal movement.
> However, in this pursuit, we may end up requiring multiple transitions to get
> a node in the right state for a given partition.
> We can fix this by refusing to prefer nodes as they come up, and then revert
> to the existing strategy once their current state contains a replica.
