> ----------------------------------------------------------
>
> Key: SPARK-45601
> URL: https://issues.apache.org/jira/browse/SPARK-45601
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.2.3
> Reporter: JacobZheng
> Priority: Major
> Fix For: 3.3.0
>
>
> I am encountering stackoverflow errors while executing the following test
> case. I looked at the source code and it is ExtractWindowExpressions not
> extracting the window correctly and encountering a dead loop at
> resolveOperatorsDownWithPruning that is causing it.
> {code:scala}
> test("agg filter contains window") {
> val src = Seq((1, "b", "c")).toDF("col1", "col2", "col3")
> .withColumn("test",
> expr("count(col1) filter (where min(col1) over(partition by col2
> order by col3)>1)"))
> src.show()
> }
> {code}
> Now my question is this kind of in agg filter (window) is the correct usage?
> Or should I add a check like spark sql and throw an error "It is not allowed
> to use window functions inside WHERE clause"?
