Tsz Wo Nicholas Sze commented on HDFS-7411:
-------------------------------------------
> Because of this, I do not see any advantage to keeping this old code around.
> ...
Users are familiar with the existing behavior so that we have to keep the old

> I still plan to commit tomorrow.
-1 on the patch.
> Refactor and improve decommissioning logic into DecommissionManager
