> We'd like to remove DataFrame RDD operations like {{map}}, {{filter}}, and 
> {{foreach}} because:
> # After making DataFrame a subclass of {{Dataset\[Row\]}}, these methods 
> conflicts with methods in Dataset.
> # By returning RDDs, they are semantically improper.
> It's trivial to remove them since they simply delegates to methods of 
> {{DataFrame.rdd}}.
