Matt Foley commented on HADOOP-7314:

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'
