I am doing some practices, for some questions, there could be various solutions, for example, I can use RDD operations to do some filtering, sorting, and grouping; with DataFrame and SparkSQL, it is even easier to me to get the same result. My question is will there be a requirement in the exam that some questions must be resolved using RDD, not DataFrame+SparkSQL. or vice versa? Thank you.
