Hi @jomenxiao. Thanks for your PR.

I'm waiting for a kubeflow 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.

Hi @jomenxiao, not sure are you still working on this. Our team is working on the Kubeflow 1.5 distribution on IBM Cloud and we see this issue on Kubernetes 1.22. Since we want to fix it before the Kubeflow 1.5 release, we added our fixes at PR #7273 that could potentially fix this issue. But feel free to incorporate our changes into this PR since you have this opened first.
