YifanZhang updated KUDU-2914:
-----------------------------
Description: 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'. (was: 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 master kick out . This can be
achieved by rebalance tool to support specifying 'blacklist_tservers'.)
