------------------------------------
Got it. My apologies, you're right that I missed the later changes. And I see
you uploaded Attachment HADOOP-7314-0.20s.patch [12486477] at the same time as
the trunk patch.
@Jeff, please attach the output of a local test-patch run for it under .20.205
branch.
@Jitendra, can you please review the deltas? Thanks.

> 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.
