Internally, Scala will generate the code as
convertListToMyList(List("apple","orange","cherry")).toDF("fruit")

I am wondering why the list in scala spark can be converted into a
dataframe directly?
scala> val df = List("apple","orange","cherry").toDF("fruit")
*df*: *org.apache.spark.sql.DataFrame* = [fruit: string]
scala> df.show
+--+
| fruit|
+--+
| apple|
|orange|
|cherry|
+--+
