Average of each RDD in Stream

[Laeeq Ahmed]

Hi,

I use the following code for calculating average. The problem is that the 
reduce operation return a DStream here and not a tuple as it normally does 
without Streaming. So how can we get the sum and the count from the DStream. 
Can we cast it to tuple?


val numbers = ssc.textFileStream(args(1))
    val sumandcount = numbers.map(n => (n.toDouble, 1)).reduce{ (a, b) => (a._1 
+ b._1, a._2 + b._2) }
    sumandcount.print()
