> The generic options have always been this:
> {noformat}
> Generic options supported are
> -conf <configuration file> specify an application configuration file
> -D <property=value> use value for given property
> -fs <local|namenode:port> specify a namenode
> -jt <local|resourcemanager:port> specify a ResourceManager
> -files <comma separated list of files> specify comma separated files to be
> copied to the map reduce cluster
> -libjars <comma separated list of jars> specify comma separated jar files
> to include in the classpath.
> -archives <comma separated list of archives> specify comma separated
> archives to be unarchived on the compute machines.
> The general command line syntax is
> bin/hadoop command [genericOptions] [commandOptions]
> {noformat}
> However, almost all the hadoop command help follow an unwritten style which
> is similar to man page descriptions.
> This is the proposed improvement.
