> 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
