    Description

      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.
