> 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

> 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).
