> Key: SPARK-35246
> URL: https://issues.apache.org/jira/browse/SPARK-35246
> Project: Spark
> Issue Type: Bug
> Components: Structured Streaming
> Affects Versions: 3.0.0, 3.1.0
> Reporter: Jose Torres

> Priority: Major
> Fix For: 3.2.0

> The UnsupportedOperationChecker currently rejects streaming intersects only if both sides are streaming, but they don't work if even one side is streaming. The following simple test, for example, fails with a cryptic None.get error because the state store can't plan itself properly.
> {code:java}
> test("intersect") {
> val input = MemoryStream[Long]
> val df = input.toDS().intersect(spark.range(10).as[Long])
> testStream(df) (
> AddData(input, 1L),
> CheckAnswer(1)
> )
> }
> {code}
