> Check if the same ExprId refers to the unique attribute in logical plans
> ------------------------------------------------------------------------

> Key: SPARK-32741
> URL: https://issues.apache.org/jira/browse/SPARK-32741
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.1.0
> Reporter: Takeshi Yamamuro
> Priority: Major
>
> Some plan transformations (e.g., `RemoveNoopOperators`) implicitly assume the
> same `ExprId` refers to the unique attribute. But, `RuleExecutor` does not
> check this integrity between logical plan transformations. So, this ticket
> targets at adding this check in `isPlanIntegral` of `Analyzer`/`Optimizer`.
