> ---------------------------------------------------
>
> Key: SPARK-36686
> URL: https://issues.apache.org/jira/browse/SPARK-36686
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.1.2
> Reporter: Andrew
> Assignee: Apache Spark
> Priority: Major
>
> SimplifyConditionalsInPredicate rule is not null-safe and leads to incorrect
> results
>
> ex. IF(cond, trueVal, true) => OR(NOT(cond), trueVal) rewrite is invalid when
> cond is null.
> LHS: IF(null, trueVal, true) => true
> RHS: OR(NOT(null), trueVal) => OR(NULL, trueVal)
