Linhong Liu created SPARK-36148:
-----------------------------------
Summary: Missing validation of regexp_replace inputs
Key: SPARK-36148
URL: https://issues.apache.org/jira/browse/SPARK-36148
Project: Spark
Issue Type: Task
Components: SQL
Affects Versions: 3.3.0
Reporter: Linhong Liu
sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/expressions/regexpExpressions.scala
overrides checkInputDataTypes, but it doesn't call super.checkInputDataTypes,
so basic type checking is disabled.
{code:java}
scala> spark.sql("""select regexp_replace(collect_list(1), "1",
"2")""").collect()
