Hi @knarayan. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

we don't usually accept merge commits. Can you please rebase?

Yup, there is a prow plugin to fail on merge commit. Let me find the prow config and enable it in scheduler-plugins' CI.

Interesting... this has been enabled https://github.com/kubernetes/test-infra/blob/de81fb13d864ccbd974e73825919a84693dca732/config/prow/plugins.yaml#L1544

I created #637 to track the netlify issue.

hi @knarayan, I have checked your branch, and it seems that your branch is far way behind the master, You have to do the rebase to base on top of the master from this sigs repo.

[zwpaper]

@knarayan it seems that you did a wrong rebase?

I would suggest you create a brand new branch from sigs/scheduler-plugins, and cherry-pick(sorry for involving one more new command) your commit to the new branch, and then you could force push it to the branch here.

@zwpaper I suppose that it is fixed now. Thank you.
