Lefty Leverenz commented on HIVE-7111:
--------------------------------------
Does this need documentation? If it does, perhaps it belongs here:
* [Hive Outer Join Behavior |
https://cwiki.apache.org/confluence/display/Hive/OuterJoinBehavior]
But it doesn't seem related to any of this:
* [Join Optimization |
https://cwiki.apache.org/confluence/display/Hive/LanguageManual+JoinOptimization]
> Extend join transitivity PPD to non-column expressions
