> 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.
