**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** I overcomplicated the design of the FilterNullJoinKey rule. There is no need to check for a combination of null and non-null join keys. Instead, we just need to add filters for any join key that is nullable. **Describe the solution you'd like** Just add filters for nullable keys on either side. **Describe alternatives you've considered** None **Additional context** None -- This is an automated message from the Apache Git Service.
