ytjia / Spark to calculate Avg

Created October 30, 2014 16:39

Calculate average value in spark.

	var data = sc.parallelize(Seq(("A", 2), ("A", 4), ("B", 2), ("Z", 0), ("B", 10)))
	// data: org.apache.spark.rdd.RDD[(java.lang.String, Int)] = ParallelCollectionRDD[31] at parallelize at <console>:12

	val avgValue = data.mapValues((_, 1)
	.reduceByKey((x, y) => (x._1 + y._1, x._2 + y._2))
	.mapValues{ case (sum, count) => (1.0 * sum) / count }
	.collectAsMap()
	// avgValue: scala.collection.Map[java.lang.String,Double] = Map(Z -> 0.0, B -> 6.0, A -> 3.0)
