> The shuffle audit logger currently logs the job ID and reducer ID but nothing
> about the size of the requested transfer. It calculates this as part of the
> HTTP response headers, so it would be trivial to log the response size. This
> would be very valuable for debugging network traffic storms from the shuffle
> handler.
