<p>The present invention provides a computer implemented method for performing an application specific operation on a dataset over a distributed computing system. The computer implemented method includes collecting a set of application specific refining data present in a data stream of the dataset in a first map phase by the distributed computing system, resetting the data stream of the dataset to a beginning position by the distributed computing system, and generating one or more resultant data elements using the set of application specific refining data in a second map phase, by the distributed computing system.</p> |
