Mikhail Antonov commented on HBASE-13336:
-----------------------------------------

[~apurtell] sorry, never got my hands on it. If it's relevant I probably would just unassign
it from myself and leave it here, otherwise we can resolve?

> The AccessController and VisibilityController do different things regarding protecting
their meta tables. The AC allows schema changes and disable/enable if the user has permission.
The VC unconditionally disallows all admin actions. Generally, bad things will happen if these
meta tables are damaged, disabled, or dropped. The likely outcome is random frequent (or constant)
server side op failures with nasty stack traces. On the other hand some things like column
family and table attribute changes can have valid use cases. We should have consistent and
sensible rules for protecting security meta tables.
