bq. This portion of the patch is actually for trunk only. The 0.20s patch for
MAPREDUCE-2489 contains all the necessary changes for 0.20.205
I assumed that meant this patch for HADOOP-7314 did not need to be back-ported.
Is MAPREDUCE-2489 not actually inclusive?

> 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.
