> Reporter: Tsz-wo Sze
> Assignee: Shashikant Banerjee
> Priority: Major
>
> In HDFS-15480, the behavior of deleting the non-earliest snapshots is
> changed to marking them as deleted in XAttr but not actually deleting them.
> The users are still able to access the these snapshots as usual.
> In this JIRA, the marked-for-deletion snapshots are hided so that they become
> inaccessible
> to users.
