Sorry I should've attached an example first. `[[], []]` input in Scala side is as below ```scala scala> val rdd=sc.parallelize(List(List(), List())) rdd: org.apache.spark.rdd.RDD[List[Nothing]] = ParallelCollectionRDD[11] at parallelize at <console>:23 scala> val df = spark.createDataFrame(rdd=rdd) df: org.apache.spark.sql.DataFrame = [value: array<void>] scala> df.show() +-----+ |value| +-----+ | []| | []| +-----+ ``` I may add a test. Let me know if you have other concerns. Thanks @zhengruifeng . -- This is an automated message from the Apache Git Service.
