Aaron T. Myers commented on HDFS-4148:
--------------------------------------
I'm not sure I agree with throwing a SnapshotException in all these cases. I
think it makes sense to just throw a normal AccessControlException when an
attempt is made to make modifications to an RO snapshot, much as an attempt to
modify an RO snapshot in WAFL or ZFS just results in EACCESS.
Thoughts?
