I am fine if you want to fix it. You can put it in `OrcSuite`. Then,
running the following command to verify whether it passes or not:
> build/sbt -Phive "hive/test-only
org.apache.spark.sql.hive.orc.OrcSourceSuite"
```scala
test("prevent all column partitioning") {
withTempDir { dir =>
val path = dir.getCanonicalPath
val e = intercept[AnalysisException] {
spark.range(10).write.format("orc").mode("overwrite").partitionBy("id").save(path)
}.getMessage
assert(e.contains("Cannot use all columns for partition columns"))
}
}
```
