Hi folks, Version: Hadoop 0.20.205.
My reducer can be optimized if I can get a good estimate on how many records are produced by the mappers, that is, if I can get the MAP_OUTPUT_RECORDS counter (or its equivalent) in my reducer. However, I tried and always got 0, guess the counters are not passed to the reducer context. Anybody has encountered the same requirement? And any pointers on that? Appreciate your help. Thanks, James
