-----------------------------------------

             Summary: Do not print usage on wrong command line
                 Key: SQOOP-1212
                 URL: https://issues.apache.org/jira/browse/SQOOP-1212
             Project: Sqoop
          Issue Type: Improvement
    Affects Versions: 1.4.4
            Reporter: Jarek Jarcec Cecho
            Assignee: Jarek Jarcec Cecho
            Priority: Minor
             Fix For: 1.4.5


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).
