Hi, I was trying to understand how exactly the reducers find out how to fetch the data of its own partition from Map nodes. During the executions of MapReduce, I see that *file.out* is created on Map nodes, so my question is how does a reducer know what part of file.out to fetch? Is the *file.out.index* play any role? Any help is appreciated .Thanks
