Review comment:
> I tried some times in my Mac, this issue can not be reproduced by sleeping

[#27724
(comment)](https://github.com/apache/spark/pull/27724#issuecomment-607628004).
So I add an UT by this code.
You should notice that my UT is is without serde, if you want to add UT, I
think you'd better add two type UT (with serde / without serde)
