Consider the following code snippet in Spark showing a set of operations and answer the following questions: a. Will this code create a single or multi-stage DAG? Justify your response. b. What will be the result of the code execution ? data = sc.parallelize([2.5,2,3,6,6,8]) new_data = data.map(lambda x: (x, 3*x+7)) f1 = new_data filter(lambda x: x[1]> 30) f2 = new_data filter(lambda x: x[1]
