>                 URL: https://issues.apache.org/jira/browse/HIVE-14095
>             Project: Hive
>          Issue Type: Bug
>          Components: Physical Optimizer
>    Affects Versions: 2.2.0

> 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.
