RDD Transformations Day 3. flatMap(function)

Hi All,

Welcome to Day 3

Like the Hello World program, the famous Word Count problem is the starting point for data engineers learning BigData processing.
While doing the WordCount problem on Spark RDD, flatMap() transformation is very crucial as it sets the stage for (Key, Value) pair creation.
In this video, learn what is flatMap(), how it works and how it is different from the map() transformation that we learned on Day 1.
