[jira] [Created] (HIVE-8496) Re-enable statistics [Spark Branch]

Chao created HIVE-8496:
--------------------------

             Summary: Re-enable statistics [Spark Branch]
                 Key: HIVE-8496
                 URL: https://issues.apache.org/jira/browse/HIVE-8496
             Project: Hive
          Issue Type: Bug
          Components: Spark
            Reporter: Chao
            Assignee: Chao


{{AnnotatedWithStatistics}} is not activated due to a recent merge, and hence the {{SetSparkReducerParallelism}} is not activated either. This caused Hive to always use one reducer. We should re-enable statistics.
