>                 Key: HADOOP-9514
>                 URL: https://issues.apache.org/jira/browse/HADOOP-9514
>             Project: Hadoop Common
>          Issue Type: Bug
>    Affects Versions: 3.0.0, 2.0.4-alpha
>            Reporter: Thomas Graves
>              Labels: usability
>
> 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.
