> Ordered snapshot deletion is a configurable feature. In this JIRA, a conf is
> added.
> When the feature is enabled, only the earliest snapshot can be deleted. For
> deleting the non-earliest snapshots, the behavior is temporarily changed to
> throwing an exception in this JIRA. In HDFS-15480, the behavior of deleting
> the non-earliest snapshots will be changed to marking them as deleted.
