Chris Nauroth commented on MAPREDUCE-5021:
------------------------------------------
{{FileUtil#createJarWithClassPath}}, currently only on branch-trunk-win,
contains code to take a path of the form /dir/* and translate it to a list of
every jar file in /dir. I've tested this code on both Mac and Windows, though
the code path is only live for Windows right now.
The method isn't exactly suitable for the feature described here, but it might
be an opportunity for refactoring and reuse.

> Reporter: Sandy Ryza

> As adding a directory of jars to the class path is a common use for the
> distributed cache it would be easier on API consumers if they were able to
> call a method that would add all the the files in a directory for them.
