Lars Hofhansl updated HBASE-4263:
---------------------------------
Attachment: 4263.txt
For what's it worth, here's a patch.
It just adds a new config option: hbase.coprocessor.user.region.classes, for
coprocessor classes to be only loaded for user tables.
For the record, I am not trying to cripple coprocessors or have any other
agenda, nor am I saying anything about the coprocessor architecture in general
(the fact that this patch is only 7 lines speaks for the thought-out design).
It's a great feature that we are planning to use extensively.
I think this a fair and simple enhancement. Nobody has to use the new config
option.
For us it would be helpful.

> 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.
