    Description

      The idea of HDFS-11069 is good. But it seems to cause confusion for administrators when they issue commands like hdfs diskbalancer, or hdfs dfsadmin, because this change of behavior is not documented properly.

      I suggest we document a recommended way to kinit (e.g. kinit as hdfs/host1@host1.EXAMPLE.COM, rather than hdfs@EXAMPLE.COM), as well as documenting a notice for running privileged DataNode commands in a Kerberized clusters
