> 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.
