Output:

Solution:

//Consider here some list 

val data = List("mango","apple","mango","orange","apple","banana")

//First we need to make rdd.

val rdd_data = sc.parallelize(data)

//Flatten data

val flat_data = rdd_data.flatMap(x=>x.split(" "))

//add suffix on all as 1

val suf_data = flat_data.map(x=>(x,1))

//reduced and count data

val word_count = suf_data.reduceByKey((x,y)=>x+y)

//print data

word_count.foreach(println)
