scala> val rdd1 = sc.parallelize(List(1,2,3,4,5))                           -  Creating RDD

scala> val rdd2 = rdd1.map(x => (x+3))                                      - Creating new RDD from existing RDD "Transformation"

scala> rdd2.collect                                                                       - Action will show the Array(4,5,6,7,8)

                                                                                                        (it represent added by 3 with 1st rdd(rdd1), i,e (1+3), (2+3), (3+3) ....

Hope it helps!
