--------------------------------------

             Summary: Document the impact of HDFS-11069 (Tighten the authorization of datanode
RPC)
                 Key: HDFS-12372
                 URL: https://issues.apache.org/jira/browse/HDFS-12372
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Wei-Chiu Chuang
            Assignee: Wei-Chiu Chuang


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
