Eric Badger commented on YARN-9818:
-----------------------------------
This is from a few years ago so I don't quite remember the details, but from
what I remember, the test was passing back then. The problem was that the test
wasn't testing what it said it was. This patch was to fix the test so that it
would accurately test what it was looking to test. But the patch was never
reviewed/committed
> test_docker_util.cc:test_add_mounts doesn't correctly test for parent dir of
> container-executor.cfg

> The code attempts to mount a directory that is a parent of
> container-executor.cfg. However, the docker.allowed.[ro,rw]-mounts settings
> in the container-executor.cfg don't allow that directory. So the test isn't
> ever getting to the code where we disallow the mount because it is a parent
> of container-executor.cfg. The test is disallowing it because the mount isn't
> in the allowed mounts list.
