Apache Spark reassigned SPARK-34420:
------------------------------------
Assignee: Apache Spark (was: L. C. Hsieh)
> Throw exception if non-streaming Deduplicate is not replaced by aggregate
> -------------------------------------------------------------------------
>
> Key: SPARK-34420
> URL: https://issues.apache.org/jira/browse/SPARK-34420
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: L. C. Hsieh
> Assignee: Apache Spark
> Priority: Minor
>
> We replace some operations in the query optimizer. For them we throw some
> exceptions accordingly in query planner if these logical nodes are not
> replaced. But `Deduplicate` is missing and it opens a possible hole. For code
> consistency and to prevent possible unexpected query planning error, we
> should add similar exception case to query planner.
