Hi, What do you mean by "shuffled bytes [to] the mappers"? If you mean "from", it is "Reduce shuffle bytes" you look for; otherwise, you may be looking for the per-map counter of "Map output bytes".
Per-partition counters can be constructed on the user side if needed, by pre-computing the partition before emit (using the same partitioner) and counting up the bytes of your objects for its counter.
