Rui Li commented on HIVE-17193:
-------------------------------
Yes I think so. We don't consider DPP when we combine map works in
CombineEquivalentWorkResolver. This is wrong because if two map works are to be
pruned by different DPP sinks, their outputs are probably different and
shouldn't be combined.
> HoS: don't combine map works that are targets of different DPPs
