      Description

      Let's say current working directory is set to "/"  (FileSystem.setCurrentWorkingDirectory()) and there is "/test" folder on HDFS.

      when I call

      org.apache.hadoop.fs.shell.PathData.expandAsGlob("test", new Configuration());
      
      

      (the relative path to test is an intention)

      then I get PathData with a "../test" path. But such path is invalid. The problem is probably inside Path.relativize method, where for "/" and "test" the "../test" is produced.

       

      What I really  want is to call "rm -R test" command with cwd set to root ("/"), but it won't work because command expands it to invalid path (DFSUtil.isValidName(result) is false).

      Using relative paths will work fine for another cwd except the root. This is just the only special case for which it fails.

      Stacktrace attached for more details.
