Thanks @ronensc That's good to know!

I don't think it's worth backporting, but I did redo these test cases for mcad v2 to be robust against different cluster sizes in https://github.com/project-codeflare/mcad/pull/83

More investigation is required as to why these tests are failing. Closing this PR.
