Subject Sorting algorithm
Date Fri, 16 Mar 2012 18:05:37 GMT

Which is the sorting algorith used in map-reduce to sort the data set in
the shuffling stage i.e after the mapped for each split up of the entire
dataset. I understand that it is merge sort for sure. But is there
modification in the algorithm in specific?  By this I mean more what are
the other details on the algorithm.

Thanks in advance.
