Class CommandLineOptions

java.lang.Object

org.apache.drill.yarn.client.CommandLineOptions

public class CommandLineOptions
extends Object

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.
