Josh Elser commented on ACCUMULO-2016:
--------------------------------------
Who has permissions to even add an iterator to the default namespace? Only
{{root}} I would assume?
If it's only root, and we're thinking about"production-esque systems with
multiple users properly corralled into their own namespaces, only the root user
could even do this, which makes me think the risk of something adverse
happening is small?
I can't help but think if we enforce this limitation programmatically, we'll
just end up creating/finding some use case which invalidates the assumption.
> Default namespace should not allow any configurations

> The bug with the default namespace having versioning iterators got me
> thinking. We shouldn't allow any iterators, or any special configurations,
> for the default namespace. I think it should be a special case namespace, and
> if people want configurations for all tables, they should all be in a
> namespace.
