--------------------------------------
Sure, I can see the benefit of another config parameter for ease of use.
Thanks Lars.
> Prevent RegionObservers from interfering with system tables.

> Project: HBase
> Issue Type: Bug
> Components: coprocessors
> Affects Versions: 0.92.0
> Reporter: Lars Hofhansl
> Priority: Minor
> Fix For: 0.92.0

>
> It turns out that a RegionObserver can interfere with - ROOT - and .META.
> That seems weird and should be prevented.
> (The one use case for this that I could come up with is access control by
> Region by intercepting actions on .META., and I don't think that's a
> particularly strong use case).
> I'll attach a patch as soon as I get to it.
