Ah, I think he meant this below:
- Parquet
```scala
val emptyDf = spark.range(10).limit(0).toDF()
emptyDf.write
.format("parquet")
.save(path.getCanonicalPath)
val copyEmptyDf = spark.read
.format("parquet")
.load(path.getCanonicalPath)
copyEmptyDf.printSchema()
```
```
root
|-- id: long (nullable = true)
```
- ORC (with this PR)
```scala
val emptyDf = spark.range(10).limit(0).toDF()
emptyDf.write
.format("orc")
.save(path.getCanonicalPath)
val copyEmptyDf = spark.read
.format("orc")
.load(path.getCanonicalPath)
copyEmptyDf.printSchema()
```
```
root
```
