So there's good news and bad news.

👍 The good news is that everyone that needs to sign a CLA (the pull request submitter and all commit authors) have done so. Everything is all good there.

😕 The bad news is that it appears that one or more commits were authored by someone other than the pull request submitter. We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that here in the pull request.

Note to project maintainer: This is a terminal state, meaning the cla/google commit status will not change from this State. It's up to you to confirm consent of the commit author(s) and merge this pull request when appropriate.

the benefit / cost for this PR is a bit low so it is really low priority for now. I am just submitting for view only.

Please sync. Can you pick a reviewer (other than me :)) I'd like to start spreading the review workload around.

@jlewi any idea why the link gave by bot was invalid?

@jimexist If you see that error

Unable to load build details from gs://kubernetes-jenkins/pr-logs/pull/kubeflow_testing/35/kubeflow-testing-presubmit/56

It typically means the prow job didn't make it as far as actually uploading any results to GCS.

So typically in this case you can trigger the test and then look for the job in the prow job dashboard. From there you can grab the actual pod logs. These get garbage collected pretty soon after the job finishes so you need to try to catch it in the act.

Here's the link to the prow jobs dashboard

Most likely that means there is a problem running the workflow and it never gets far enough to upload the results to GCS.

You need to try to look at the pod logs for the test; these are ephmeral so you need to grab them shortly after running your job.

You can find them here

@jlewi maybe due to lack of authorization, what i saw in https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/pr-logs/pull/kubeflow_testing/35/kubeflow-testing-presubmit/99/ was:

I was able to get access to the logs. Here's the failure
