> 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.
