Description

IMPALA-2730 claims there's a test infra bug, but it's actually a pytest bug. Our version of pytest is 2.7.2, and the bug is fixed in 2.7.3. Pytest is up to 2.8.7. While the less risky change is to upgrade to 2.7.3, we're likely to do the same amount of testing for that as we would upgrading to pytest 2.8.x. Maybe we should just do one big upgrade. But not until after code freeze at the earliest.
