[jira] [Created] (HIVE-9137) Turn off Hive's PredicateTransitivePropagate optimizer when cbo is on

Ashutosh Chauhan created HIVE-9137:
--------------------------------------

             Summary: Turn off Hive's PredicateTransitivePropagate optimizer when cbo is on
                 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
            Assignee: 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.
