>                 Key: SPARK-30858
>                 URL: https://issues.apache.org/jira/browse/SPARK-30858
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL
>    Affects Versions: 3.0.0
>            Reporter: Herman van Hövell
>            Priority: Blocker
>
> {{IntegralDivide}}'s dataType depends on the value of 
> {{SQLConf.get.integralDivideReturnLong}}. This is a problem because the 
> configuration can change between different phases of planning, and this can 
> silently break a query plan which can lead to crashes or data corruption.
