-----------------------------------
Summary: 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: L. C. Hsieh
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.
