> Before 1.3.0, {{SchemaRDD.id}} works as a unique identifier of each {{SchemaRDD}}. In 1.3.0, unlike {{SchemaRDD}}, {{DataFrame}} is no longer an RDD, and {{DataFrame.rdd}} is actually a function which always return a new RDD instance. Making {{DataFrame.rdd}} a {{lazy val}} should bring the unique identifier back.
