    Description

      HBASE-15332 added a doc note about how to use HDFS-6133, but the steps it adds are incorrect. The specific balancer command provided in the doc note is incorrect and not required.

      Since HBase uses favored nodes features internally (HBASE-7932), and HBASE-7942 extended that information to cover HDFS hinting too, the only step required in the doc note is to enable the pinning feature DN-side.
