             Summary: Scale down stats for plan when DPP/SJ is applied
                 Key: HIVE-20957
                 URL: https://issues.apache.org/jira/browse/HIVE-20957
             Project: Hive
          Issue Type: Improvement
          Components: Physical Optimizer, Statistics
            Reporter: Jesus Camacho Rodriguez


Currently, this scale down only happens for TS itself when SJ is applied 
(HIVE-20775). It would be better to implement an approach that applies the 
reduction to the TS operator for DPP/SJ and propagates the complete stats over 
the plan accordingly.
