[jira] [Created] (HIVE-14095) Simplify decision logic to execute RS dedup for Join operators

Jesus Camacho Rodriguez created HIVE-14095:
----------------------------------------------

             Summary: Simplify decision logic to execute RS dedup for Join operators
                 Key: HIVE-14095
                 URL: https://issues.apache.org/jira/browse/HIVE-14095
             Project: Hive
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: Jesus Camacho Rodriguez


Currently, three different HiveConf properties need to be set to a certain value in order to trigger RS dedup optimization for Join operators. This means that for instance, when auto convert join is on (default value), RSdedup is off for Join operators.

We should explore this further and simplify this logic.
