> Project: Hadoop HDFS

> 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/ho...@host1.example.com, rather than h...@example.com), as well as
> documenting a notice for running privileged DataNode commands in a Kerberized
> clusters
