Rakesh R commented on HDFS-8643:
--------------------------------

Thanks [~xyao] for the reviews and the pointer to {{lsSnapshottableDir}} cmd. I've tried to
incorporate the changes here and attached another patch.

> The idea of this jira to enhance {{SnapshottableDirectoryStatus}} by adding {{snapshotNames}}
attribute into it, presently it has the {{snapshotNumber}}. IMHO this would help the users
to get the list of snapshot names created. Also, the snapshot names can be used while renaming
or deleting the snapshots.

>   /**
>    * @return Snapshot names for the directory.
>    */
>   public List <String> getSnapshotNames() {
>     return snapshotNames;
>   }
> {code}
