    Description

      Improved the speed of KMeans by passing only cluster ID from mapper to reducer. Previously, whole Cluster Info as formatted s`tring was being sent.
      Also removed the implicit assumption of Combiner runs only once approach and the code is modified accordingly so that it won't create a bug when combiner runs zero or more than once.
