the issue is likely connected to parquet file reader, I can reproduce with
specific parquet created by `makeParquetFileAllPrimitiveTypes`. The same data
and data types written by `spark.parquet.write` works fine.
The localized test is
```
test("array_intersect1") {
// TODO test fails if scan is auto
// https://github.com/apache/datafusion-comet/issues/2174
withSQLConf(
CometConf.COMET_NATIVE_SCAN_IMPL.key ->
CometConf.SCAN_NATIVE_ICEBERG_COMPAT,
CometConf.COMET_EXPR_ALLOW_INCOMPATIBLE.key -> "true") {
spark.read.parquet("/tmp/test.parquet").createOrReplaceTempView("t1")
sql("select _2, _9, _10 from t1").show(false)
checkSparkAnswerAndOperator(sql("select array(_2), array(_9, _10) from
(select _2, _9, _10 from t1)"))
}
}
```
