peter-toth opened a new pull request, #39676:
URL: https://github.com/apache/spark/pull/39676
### What changes were proposed in this pull request?
This is a small correctness fix to
`DataSourceUtils.getPartitionFiltersAndDataFilters()` to handle filters without
any referenced attributes correctly. E.g. without the fix the following query
on ParquetV2 source:
```
spark.conf.set("spark.sql.sources.useV1SourceList", "")
spark.range(1).write.mode("overwrite").format("parquet").save(path)
df = spark.read.parquet(path).toDF("i")
f = udf(lambda x: False, "boolean")(lit(1))
val r = df.filter(f)
r.show()
```
returns
```
+---+
| i|
+---+
| 0|
+---+
```
but it should return with empty results.
The root cause of the issue is that during `V2ScanRelationPushDown` a filter
that doesn't reference any column incorrectly identified as partition filter.
### Why are the changes needed?
To fix a correctness issue.
### Does this PR introduce _any_ user-facing change?
Yes, fixes a correctness issue.
### How was this patch tested?
Added new UT.
