YifanZhang commented on KUDU-2914:
----------------------------------
Agreed with the three steps of decommissioning tablet servers.
Actually I have worked on improving rebalance tool to support moving all
replicas from the tablet server, we use the tool many times on our production
clusters, I will submit the codes soon.

> Project: Kudu
> Issue Type: Improvement
> Components: CLI
> Reporter: YifanZhang
> Priority: Minor
>
> 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'.
