More Actions - Reduce()
var seq = sc.parallelize(1 to 100)
def sum(x: Int, y:Int):Int = {return x+y}
var total = seq.reduce(sum);
and
sum(1,3)
Using reduce for avg()
var seq = sc.parallelize(Array(3.0, 7, 13, 16, 19))
def avg(x: Double, y:Double):Double = {return (x+y)/2}
var total = seq.reduce(avg);
