> Key: SPARK-24381
> URL: https://issues.apache.org/jira/browse/SPARK-24381
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.2
> Reporter: Miles Yucht
> Priority: Major
> Fix For: 2.4.0
>
>
> Today, the unit test coverage for NOT IN queries in SubquerySuite is somewhat
> lacking. There are a couple test cases that exist, but it isn't necessarily
> clear that those tests cover all of the subcomponents of null-aware anti
> joins, i.e. where the subquery returns a null value, if specific columns of
> either relation are null, etc. Also, it is somewhat difficult for a newcomer
> to understand the intended behavior of a null-aware anti join without great
> effort. We should make sure we have proper coverage as well as improve the
> documentation of this particular subquery, especially with respect to null
> behavior.
