      This change introduces a new configuration key used to throttle decommissioning work, "dfs.namenode.decommission.blocks.per.interval". This new key overrides and deprecates the previous related configuration key "dfs.namenode.decommission.nodes.per.interval". The new key is intended to result in more predictable pause times while scanning decommissioning nodes.

      Description

      Would be nice to split out decommission logic from DatanodeManager to DecommissionManager.
