      This change adds two new configuration parameters.
      # {{dfs.namenode.invalidate.work.pct.per.iteration}} for controlling deletion rate of blocks.
      # {{dfs.namenode.replication.work.multiplier.per.iteration}} for controlling replication rate. This in turn allows controlling the time it takes for decommissioning.

      Please see hdfs-default.xml for detailed description.

    Description

      It would be good to have the equivalent change of HDFS-3475 in 1.x to allow customization of replication rate.
