Xuefu Zhang commented on HIVE-5895:
-----------------------------------
I understand that the current division can possibly return infinity or NaN.
However, this seems to me a bug (or bad behavior) rather than norm. To me, they
provide no more information than NULL. Such complication comes due to hive
having no consistent error handling. HIVE-5348 and HIVE-5660 are to address
those issues. For this particular case, I wouldn't be crying if NULL is
returned for both infinity or NaN, especially if it makes the life easier.
> vectorization handles division by zero differently from normal execution
