[jira] [Updated] (HBASE-4263) Prevent RegionObservers from interfering with system tables.

["Lars Hofhansl (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-4263?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lars Hofhansl updated HBASE-4263:
---------------------------------

    Description: 
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.

  was:
It turns out that a RegionObserver can interfere with {noformat}-ROOT-{noformat}  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).
