    Description

      It would be nice if libhdfs exposed rename2. This version of rename is much more verbose about any errors that occur-- it throws AccessControlException, FileAlreadyExists, FileNotFoundException, ParentNotDirectoryException, etc.

      The original rename returns false in many distinct cases, making it ambiguous exactly what the problem was.

      For something like fuse_dfs, it is very important to return the correct errno code when an error has occurred. rename2 would allow us to do that.
