Sergey Shelukhin commented on HIVE-5895:
----------------------------------------
Actually regular division can also produce infinities according to the spec, so
in order to preserve the logic that avoids the null-value-setting loop when
batch has no nulls, one would have to also pass in input to do the if for
entire batch anyway if there's at least one 0 on the right side. So there will
be a lot of code change for this case.
> vectorization handles division by zero differently from normal execution
