Andrew Purtell commented on HBASE-11757:
----------------------------------------
Ok unassigned.
Copying default methods into a common abstract base is all I have in mind. At
least maintaining consistency among some duplicated code would fall on us
rather than unfortunate CP implementors.
After HBASE-11125 this won't be an issue because we would hide hooks from
implementations unless they specifically register interest.
> Provide a common base abstract class for both RegionObserver and

>
> Some security coprocessors extend both RegionObserver and MasterObserver,
> unfortunately only one of the two can use the available base abstract class
> implementations. Provide a common base abstract class for both the
> RegionObserver and MasterObserver interfaces. Update current coprocessors
> that extend both interfaces to use the new common base abstract class.
