wForget opened a new issue, #1574:
URL: https://github.com/apache/datafusion-comet/issues/1574
### Describe the bug
Currently `native_datafusion/native_iceberg_compat` scans are
case-sensitive, which may be inconsistent with vanilla spark.
test case:
```
test("test V1 parquet scan uses native_iceberg_compat -- case
insensitive") {
withTempPath { path =>
spark.range(10).toDF("a").write.parquet(path.toString)
Seq(CometConf.SCAN_NATIVE_DATAFUSION,
CometConf.SCAN_NATIVE_ICEBERG_COMPAT).foreach(scanMode => {
withSQLConf(CometConf.COMET_NATIVE_SCAN_IMPL.key -> scanMode) {
sql("create table test (A long) using parquet options (path '" +
path + "')")
val df = sql("select A from test")
checkSparkAnswer(df)
}
})
}
}
```
error:
```
