Release Note:

Hide
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.
