      Description

      As part of MAPREDUCE-2489, we need support for having the resolve methods (for DNS mapping) throw UnknownHostExceptions. (Currently, they hide the exception). Since the existing 'resolve' method is ultimately used by several other locations/components, I propose we add a new 'resolveValidHosts' method.
