CCA175 Exam Dumps : CCA Spark and Hadoop Developer Exam

Problem Scenario 46 : You have been given belwo list in scala (name,sex,cost) for each work done.

List( ("Deeapak" , "male", 4000), ("Deepak" , "male", 2000), ("Deepika" , "female", 2000),("Deepak" , "female", 2000), ("Deepak" , "male", 1000) , ("Neeta" , "female", 2000))

Now write a Spark program to load this list as an RDD and do the sum of cost for combination of name and sex (as key)

Problem Scenario 55 : You have been given below code snippet.

val pairRDDI = sc.parallelize(List( ("cat",2), ("cat", 5), ("book", 4),("cat", 12))) val pairRDD2 = sc.parallelize(List( ("cat",2), ("cup", 5), ("mouse", 4),("cat", 12)))

operation1

Write a correct code snippet for operationl which will produce desired output, shown below.

Array[(String, (Option[lnt], Option[lnt]))] = Array((book,(Some(4},None)), (mouse,(None,Some(4))), (cup,(None,Some(5))), (cat,(Some(2),Some(2)), (cat,(Some(2),Some(12))), (cat,(Some(5),Some(2))), (cat,(Some(5),Some(12))), (cat,(Some(12),Some(2))), (cat,(Some(12),Some(12)))J

Problem Scenario 59 : You have been given below code snippet.

val x = sc.parallelize(1 to 20)

val y = sc.parallelize(10 to 30) operationl

z.collect

Write a correct code snippet for operationl which will produce desired output, shown below. Array[lnt] = Array(16,12, 20,13,17,14,18,10,19,15,11)
