[jira] [Commented] (HBASE-4263) Prevent RegionObservers from
interfering with system tables.
[ https://issues.apache.org/jira/browse/HBASE-4263?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13092197#comment-13092197 ]
Lars Hofhansl commented on HBASE-4263:
--------------------------------------
I think it is still OK to load per table coprocessors for - ROOT - and .META. as those are (presumably) specifically targeted to those tables.

> 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 string use case).
> I'll attach a patch as soon as I get to it.
