-------------------------------------
Summary: Shuffle audit logger should log size of shuffle transfer
Key: MAPREDUCE-6958
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6958
Project: Hadoop Map/Reduce
Issue Type: Improvement
Reporter: Jason Lowe
Assignee: Jason Lowe
Priority: Minor
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.
