Hi all, I have recently started using Hadoop streaming. From the documentation, I understand that by default, each line output from a mapper up to the first tab becomes the key and rest of the line is the value. I wanted to know that between the mapper and reducer, is there a shuffling(sorting) phase? More specifically, Would it be correct to assume that output from all mappers with the same key will go to the same reducer?
Thanks, Nipun
