Hi Asokan,
Actually i am working on the local version of branch-2 and doing some
experiments for my thesis ,so since working offline  not sure from where i
should get  the MAPREDUCE-4807 ? Could you please guide me how to get this
patch?

Another question is how can i monitor the mapper output to be sure it is
really unsorted ?
