Daryn Sharp commented on HADOOP-7995:
-------------------------------------
Here's a few examples of how conflicts may occur if the generic options can
appear anywhere in the cmdline:
* du -D dir
* ln -fs path
@Harsh
Do you feel this is compelling enough to close the jira?
> GenericOptionsParser ought to have better options parsing, and not pick only
> the options in the front

> Project: Hadoop Common
> Issue Type: Improvement
> Components: util
> Affects Versions: 0.23.0
> Reporter: Harsh J
> Priority: Minor
> Labels: newbie
>
> The ToolRunner provided GenericOptionsParser stops parsing known options when
> it encounters the first unknown option string in the String[] today.
> Ideally we should have it be more intelligent and sift through the whole
> array to pick up all opts, and not just the opts that are at the front of the
> invoked CLI.
