---------------------------------------
[~zoucao]
Looks like providedLibDirs assume all of the Path have to be folder rather
file. But HTTPFileSystem in hadoop doesn't support listFiles. It is also
meaningless to list a http file. I guess we should revise the function
getAllFilesInProvidedLibDirs to getAllFilesInProvidedLibPaths. The path can be
either a file or a folder. In the function getAllFilesInProvidedLibPaths, If we
find it is a http path, we assume it is a file. How do you think [~xintongsong]?
> Yarn provided lib does not work with http paths.
