Spark dataset conversion to RDD

Question

I have a Dataset [String] and you need to convert to RDD [String]. How?

Note. I recently switched from spark 1.6 to spark 2.0. Some of my clients were expecting RDD, but now Spark is giving me Dataset.

Answer 1

As stated in the scala API documentation , you can call .rddin your dataset:

val myRdd : RDD[String] = ds.rdd

Answer 2

A dataset is a strongly typed Dataframe, so both Dataset and Dataframe can use .rdd to convert to RDD.
