GenericOptionsParser is a class that interprets common Hadoop command-line options and sets them on a Configuration object for your application to use as desired. You don’t usually use GenericOptionsParser directly, as it’s more convenient to implement the Tool interface and run your application with the ToolRunner, which uses GenericOptionsParser internally.
