-------------------------------------------
Yeah it is. Thanks for pointing this out.
> Pmod should not throw a divide by zero exception
> ------------------------------------------------
>
> Key: SPARK-21630
> URL: https://issues.apache.org/jira/browse/SPARK-21630
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.2, 2.1.1, 2.2.0
> Reporter: Herman van Hovell
>
> Pmod currently throws a divide by zero exception when the right input is 0.
> It should - like Divide or Remainder - probably return null.
> Here is a small reproducer:
> {noformat}
> scala> sql("select pmod(id, 0) from range(10)").show
> 17/08/03 22:36:43 ERROR Executor: Exception in task 0.0 in stage 3.0 (TID 3)
> java.lang.ArithmeticException: / by zero
> {noformat}
