Hi Harsh, That is nice if branch-2 included that .Just one thing i want to be sure about that .In this patch MAPREDUCE-4807 (branch-2) , sort in mapper is avoided ? Becouse i need a version of hadoop without sorting part in mapper and thats the reason i wanted to modify MapTask to disable the mapper sort .Do you think branch-2 is appropriate version for me ?
