> They appear to be swapped, though that is not quite the case. You can consistently see {{COMBINE_INPUT_RECORDS}} < {{COMBINE_OUTPUT_RECORDS}}, which shouldn't be possible. 
> This issue relates to TEZ-1344, which was closed due to not being reproducible, but it actually is fairly easily reproducible if you run the same job on Tez and on MR. For whatever reason, I cannot reopen that Jira, so I'm creating this one.
