Review comment:
What do you mean by `the config must be set`, @xuanyuanking ? What value do
you expect by default? Apparently, this seems to revert SPARK-25641 together
without mentioning SPARK-25641. In the PR, only SPARK-24355 is mentioned.
> No need to give a default value here, when it comes to here, the config
must be set.
