------------------------------
Summary: fix SimplifyConditionalsInPredicate to be null-safe
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
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)
