Hi everyone, how can i know the keys that are associated to a particular reducer in the setup method? Let's assume in the setup method to read from a file where each line is a string that will become a key emitted from mappers. For each of these lines I would like to know if the string will be a key associated with the current reducer or not.
I read something about mapred.task.partition and mapred.task.id, but I didn't understand the usage. Thanks, Alberto -- Alberto Cordioli
