Description

The warning that is issued in JobSubmitter – "Use GenericOptionsParser for parsing the arguments. Applications should implement Tool for the same." – is confusing and (probably) grammatically incorrect.

This can be improved by having an updated warning message which gives clearer directions on what can be improved in the application to avoid the warning in the future.
