[jira] [Created] (HDFS-11806) hdfs journalnode command should support meaningful --help

Doris Gu created HDFS-11806:
-------------------------------

             Summary: hdfs journalnode command should support meaningful --help
                 Key: HDFS-11806
                 URL: https://issues.apache.org/jira/browse/HDFS-11806
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 3.0.0-alpha2
            Reporter: Doris Gu


Most (sub) commands support -help or -h options for detailed help while hdfs journalnode does not. What's worse, when you use "hdfs journalnode -h" to
get some help, journalnode daemon starts straightly.
