-----------------------------------
Assignee: L. C. Hsieh
> Don't insert redundant ColumnarToRowExec for node supporting both columnar
> and row output
> -----------------------------------------------------------------------------------------
>
> Key: SPARK-51474
> URL: https://issues.apache.org/jira/browse/SPARK-51474
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.0.0
> Reporter: L. C. Hsieh
> Assignee: L. C. Hsieh
> Priority: Major
>
> There is a corner case in ApplyColumnarRulesAndInsertTransitions. When a plan
> required to output rows, if the node supports both columnar and row output,
> the rule currently adds a redundant ColumnarToRowExec to its upstream. This
> ColumnarToRowExec is redundant and unnecessary.
