> Alok reported seeing the following exception when subclass of class which implements CoprocessorService is used for hbase.coprocessor.region.classes :
> {code}
> hbase(main):015:0> grant 'mktg1', 'RWC', 'iemployee'
> ERROR: org.apache.hadoop.hbase.exceptions.UnknownProtocolException: No registered coprocessor service found for name AccessControlService in region hbase:acl,,1437137157604.2daf735ea38da95e9ba249db6b63b79c.

> The root cause is in the following code of RegionCoprocessorHost:
> {code}
> for (Class<?> c : implClass.getInterfaces()) {
> if (CoprocessorService.class.isAssignableFrom(c)) {
> region.registerService( ((CoprocessorService)instance).getService() );
> }
> }
> {code}
> We currently only check the interfaces directly implemented by the underlying class.
> What should be done is to check all the interfaces implemented by class itself and its superclasses.
