Just reading this and #33154, shouldn't we enable this only w/ Kubernates (and also when it's not a Thirftserver, shall, etc.)?

Also, I think we might have to add some comments on that.

@HyukjinKwon This PR was reverted once and resubmitted #32283 (in which Thirftserver and others are excluded).

But I agree with you that we should only do this for K8s. Otherwise, it looks like a behavior change to me.

@dongjoon-hyun that pr looks unrelated, right ? Not sure if I am missing something.

Oops. It's a typo of #32283 . I tried to mention the one from @Ngone51 's comment.
