+1, LGTM. Thank you, @huaxingao and @viirya .
Merged to master.

[dongjoon-hyun]

I understand the intention, @huaxingao . But, SPARK-28441 should have enabled this test in the PR together. I changed this to as a follow-up of SPARK-28441.

[dongjoon-hyun]

Oh, I missed @HyukjinKwon 's comment.
Okay, I change the PR title back.

[huaxingao]

Thanks! @dongjoon-hyun @viirya

[HyukjinKwon]

Ah, for trackabiliy, maybe 28441 was a better choice but should be fine either way.

[viirya]

Either is fine to me.
