Drill YARN client command line options. 

 DrillYarnClient -h|--help |
                 start |
                 stop |
                 status |
                 resize [+|-]n

  • help: Prints command line usage
  • start: starts the defined cluster
  • stop: stops the defined cluster
  • resize: adds (+n), removes (-n) or resizes (n) the cluster
  • status: prints status about the cluster

This is a do-it-yourself parser because the command line parser used by Drill does not accept parameters (arguments) without a dash, and does not accept arguments (such as resize -3) with a dash.
