Description
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.
