He Yongqiang commented on HIVE-1767:
------------------------------------
When there is a dynamic partition, the merge task never gets launched. I was
trying to figure out what's happening there.
It turns out a bug in ConditionalResolverMergeFiles that leads to the size
information counted is not correct for dp queries.
Attached a patch for it.
