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 ?
