Eric Badger created TEZ-3486:
--------------------------------
Summary: COMBINE_OUTPUT_RECORDS/COMBINE_INPUT_RECORDS are not
correct
Key: TEZ-3486
URL: https://issues.apache.org/jira/browse/TEZ-3486
Project: Apache Tez
Issue Type: Bug
Reporter: Eric Badger
Assignee: Eric Badger
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.
