mapReduceAverage

Calculate Average value in WordCount MapReduce on Hadoop

The famous example of Word Count that can be found here here Shows a simple MapReduce that sets counter of words.

Here I set an example that instead of counting the words, will print out the average value of word count.

In order to do so, we changed the original program:

  • We separated between combiner and reducer (it was the same class used for both puposes)
  • We created a new reducer that accumulates the Average value accross the iterations and eventually prints the final value
