> To remove the cache of FileStatus in DFSPath (HADOOP-2565) without hurting performance,
we must use file enumeration APIs that return FileStatus[] rather than Path[].  Currently
we have FileSystem#globPaths(), but that method should be deprecated and replaced with a FileSystem#globStatus().
> We need to deprecate FileSystem#globPaths() in 0.16 in order to remove the cache in 0.17.
