    Description

      The generic options have always been this:

      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]
      

      However, almost all the hadoop command help follow an unwritten style which is similar to man page descriptions.
      This is the proposed improvement.

      Generic options supported are:
      -conf <configuration file>     specify an application configuration file
      -D <property=value>            define a value for given property
      -fs <local|namenode:port>      specify a namenode
      -jt <local|jobtracker:port>    specify a job tracker
      -files <file1,...>             specify a comma-separated list of files to be copied to the map reduce cluster
      -libjars <jar1,...>            specify a comma-separated list of jar files to be included in the classpath
      -archives <archive1,...>       specify a comma-separated list of archives to be unarchived on the compute machines
