Subject [jira] [Commented] (HIVE-16756) Vectorization: LongColModuloLongColumn throws "java.lang.ArithmeticException: / by zero"

Matt McCline commented on HIVE-16756:
-------------------------------------

[~gopalv] [~teddy.choi] Ok, you guys.  The vectorized templates that generate the division
class work for double because when you divide a double by 0 it sets the result to NaN.  But
for long since there is no NaN integer value it throws an exception.  So, I need to create
a different template for the long type that checks for a 0 denominator and doesn't perform
the integer division by 0.
