Andrew Purtell commented on HBASE-7367:
---------------------------------------

bq. I remember something like no rows in _acl_ means everyone has access.

Hmm.. We are supposed to have a default deny policy except for ROOT and META, 
which are special cased. If this is not the case, this is a big problem.

> Currently snapshot don't care about ACL...
> and in the first draft snapshots should be disabled if the ACL coprocessor is 
> enabled.
> After the first step, we can discuss how to handle the snapshot/restore/clone.
> Is saving and restoring the _acl_ related rights, the right way? maybe after 
> 3 months we don't want to give the access the guys listed in the old _acl_...
