[jira] [Created] (HADOOP-9514) Hadoop CLI's have inconsistent usages

Thomas Graves created HADOOP-9514:
-------------------------------------

             Summary: Hadoop CLI's have inconsistent usages
                 Key: HADOOP-9514
                 URL: https://issues.apache.org/jira/browse/HADOOP-9514
             Project: Hadoop Common
          Issue Type: Bug
          Components: scripts
    Affects Versions: 2.0.4-alpha, 3.0.0
            Reporter: Thomas Graves


Many of the hadoop command line interfaces (yarn/mapred/hdfs/hadoop) and subcommands have inconsistent usages, in many cases have options that don't apply (-archives/-files/-jt), and due to the usage of GenericOptionsParser print the usage as "bin/hadoop command [genericOptions] [commandOptions]" even though you were running yarn or hdfs commands.

This makes for a bad user experience and its confusing as to what options are really available and how to use them.
