Jason Dere commented on HIVE-8052:
----------------------------------
+1
Since you found the cause of the different results between MR/Tez, does that

first patch will also work?
> Vectorization: min() on TimeStamp datatype fails with error "Vector aggregate
> not implemented: min for type: TIMESTAMP"
