Harsh J commented on MAPREDUCE-4432:
------------------------------------
Gabriel,
Thanks for filing this! I agree we should improve it. Your improvement is much
nicer to read and understand as well :)
Given that GenericOptionsParser is a non-public API class, and Tool was the
real to-be-used class for users, I think we should not suggest GOP at all and
rather show the message just with Tool?
> Confusing warning message when GenericOptionsParser is not used

> Key: MAPREDUCE-4432

> 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.
