ryan rawson commented on HBASE-2229:
------------------------------------
Basically simplicity. Here is their well done example page:
http://jopt-simple.sourceforge.net/examples.html
Here is a compairson:
Options options = new Options();
options.addOption( OptionBuilder.withArgName("user")
.hasArg()
.isRequired()
.withDescription("user to use")
.create("user") );
// .. later ..
CommandLineParser clp = new GnuParser();
CommandLine line = clp.parse( opts, args );
// now read your arguments out of the 'line' object, eg:
String user = cl.getOptionValue("user");
Equivalent example in jopt-simple:
OptionParser parser = new OptionParser();
parser.accepts("user").withRequiredArg();
OptionSet options = parser.parse( args );
String user = options.valueOf("user");
/// Or if you are doing single character options:
OptionParser parser = new OptionParser( "u::" );
OptionSet options = parser.parse( args ) ;
String user = options.valueOf("user");
> convert all command line parsing to jopt simple

> what we are doing right now is wonky, we should use jopt simple, which
> attempts to emulate ye olde classic opt parsers from C in their brevity and
