---------------------------------------------
[~szehon]
{code}
public boolean process(String[] argv) {
try {
commandLine = new GnuParser().parse(options, argv);
if (commandLine.hasOption('H')) {
printUsage();
return false;
}
{code}
In the above code passing argument is handled by GnuParser class, there parse
exception we are getting, in catch block any error we are getting, showing
usage again.
{code}
catch (ParseException e) {
System.err.println(e.getMessage());
printUsage();
return false;
}
return true;
}
{code}
Better will throw parse Exception only.
Instead of printing usage again.
Based on Exception end user will come to know.
> HiveServer2 help command is not recognizing properly.
