{code:java}
// spark sql
// java encoder or kryo encoder
implicit val im = Encoders.kryo[java.util.Map[Int,
Int]].asInstanceOf[ExpressionEncoder[util.Map[Int, Int]]]
val ds = spark.createDataset(Seq(Collections.singletonMap(1,1)))
ds.show()
// +--------------------+
// | value|
// +--------------------+
// |[01 00 6A 61 76 6...|
// +--------------------+
ds.collect().foreach(println(_))
// {1=1}

ds.collect().foreach(println) is more readable than ds.show(), not sure is the
