      Description

      I am trying to remove file from BackupNode using

      hadoop fs -fs hdfs://backup.node.com:50100 -rm /README.txt

      which is supposed to fail. But it seems to be hanging forever.
      Needs some investigation. It used to throw SafeModeException if I remember correctly.
