Tsz-wo Sze commented on HDFS-15479:
-----------------------------------
[~ayushtkn], I also notice the failure recently. I am going to fix it in
HDFS-15481 by moving the conf out from DFSConfigKeys.

> 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.
