      Description

      me@gateway-hawaii-all:/mnt/host/bin$ hdfs dfsrouteradmin -ls /home/move 
      Mount Table Entries:
      Source Destinations Owner Group Mode 
      /home/move hdfs-oahu->/home/move me hadoop rwxr-xr-x

      me@gateway-hawaii-all:/mnt/host/bin$ hdfs dfsrouteradmin -ls /home/move/
      Mount Table Entries:
      Source Destinations Owner Group Mode

      me@gateway-hawaii-all:/mnt/host/bin$ hdfs dfsrouteradmin -rm /home/move/
      Cannot remove mount point /home/move/

      me@gateway-hawaii-all:/mnt/host/bin$ hdfs dfsrouteradmin -add /home/move/ hdfs-oahu /home/move/ -readonly
      Cannot add mount point /home/move/

      The slash '/' at the end should be normalized before calling the API from the CLI.

      Note: add command fails with a terminating '/' . when it is an existing entry (it checks the not-normalized value with the normalized value in the mount-table). Adding a new mount point with '/' at the end works because the CLI normalizes the mount before calling the API.
