> In JsonRDD.scalafy, we are using toMap/toList to convert a Java Map/List to a
> Scala one. These two operations are pretty expensive because they read
> elements from a Java Map/List and then load to a Scala Map/List. We can use
> Scala wrappers to wrap those Java collections instead of using toMap/toList.
