Assignment 3: SparkRDD and SparkSQL Solution

$30.00 $26.40



This assignment is very similar to Assignment #2 (kNN query) but this time you need to do it using Spark RDD and Spark SQL. In the KNN query, the input is a set of points ( ) in the Euclidean space, a query point ( ), and an integer ( ). The output is the points in that are closest to the query point . In some sense, the Spark RDD implementation would share some similarities with the Hadoop MapReduce implementation and the Spark SQL implementation would share some similarities with the Pig Latin implementation. In this assignment, you will observe the expressiveness and efficiency of Spark over Hadoop.
