Marcelo Vanzin updated SPARK-24381: ----------------------------------- Fix Version/s: (was: 2.3.2) 2.3.1 > Improve Unit Test Coverage of NOT IN subqueries > ----------------------------------------------- > > 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: 2.3.1 > > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
