bq. Summary
bq. -------
bq.
bq. 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.
