Xiaoyu Yao commented on HDFS-8643:
----------------------------------
Thanks [~rakeshr] for adding this. Patch LGTM. +1
One question: Have you thought of enhancing *lsSnapshottableDir* cmd of HDFS
CLI with additional parameter to display the snapshot name information? This
could be done in a separate JIRA?
> Add snapshot names list to SnapshottableDirectoryStatus

> 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;
> }
