> When we need to remove some tservers from a kudu cluster (maybe just for saving resources or replacing these servers with new servers), it's better to move all replicas on these tservers to other tservers in a cluster in advance, instead of waiting for all replicas kicked out and evicting new replicas. This can be achieved by rebalance tool supporting specifying 'blacklist_tservers'.
