> Key: HIVE-9137
> URL: https://issues.apache.org/jira/browse/HIVE-9137
> Project: Hive
> Issue Type: Task
> Components: CBO, Logical Optimizer
> Affects Versions: 0.15.0
> Reporter: Ashutosh Chauhan

>
> Because Calcite contains rule called {{JoinPushTransitivePredicatesRule}}
> which does exactly this. So, if cbo is on, this optimization would have
> already taken place and we won't gain anything by running this again.
