Ning Zhang commented on HIVE-1064:
----------------------------------
Carl, there are a lot of conflicts when applying this patch to the latest
trunk. It may be because of the two large patches committed recently. There
should not be further large patches in recently, can you resolve the conflicts
and resubmit a new patch? I'll start reviewing right away from there.
