> When copying files using distcp with globbed source files, all the matched
> files in the glob are copied in a single flat directory. This causes
> problems when the file structure at the source is important. It also is an
> issue when there are two files matched in the glob with the same name because
> it causes a duplicate file error at the target. I'd like to have an option
> to preserve the file structure of the source files when globbing inputs.
