Description

Currently when user enter an incorrect command line, Sqoop will print in order:

• Useful error message what has been entered wrong
• At least 200 lines long usage guide

As the usage guide will scroll the shell, the most useful information will get moved away, resulting in user confusion. I think that it will be more user friendly to stop printing the usage in case of a wrong input and display it only explicitly when user will ask for it (e.g. on sqoop import --help call).
