jose-torres opened a new pull request #32371:
URL: https://github.com/apache/spark/pull/32371
### What changes were proposed in this pull request?
The UnsupportedOperationChecker shouldn't allow streaming-batch intersects.
As described in the ticket, they can't actually be planned correctly, and even
simple cases like the below will fail:
```
test("intersect") {
val input = MemoryStream[Long]
val df = input.toDS().intersect(spark.range(10).as[Long])
testStream(df) (
AddData(input, 1L),
CheckAnswer(1)
)
}
```
### Why are the changes needed?
Users will be confused by the cryptic errors produced from trying to run an
invalid query plan.
### Does this PR introduce _any_ user-facing change?
Some queries which previously failed with a poor error will now fail with a
better one.
### How was this patch tested?
modified unit test
