             Summary: Normalize paths (automatically) when adding, removing or listing mount table entries
                 Key: HDFS-13508
                 URL: https://issues.apache.org/jira/browse/HDFS-13508
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Ekanth S


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.
