---------------------------
Resolution: Won't Fix
> Clean up the usage of EliminateSubqueryAliases
> ----------------------------------------------
>
> Key: SPARK-19722
> URL: https://issues.apache.org/jira/browse/SPARK-19722
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Xiao Li
> Assignee: Xiao Li
> Priority: Minor
>
> In the PR https://github.com/apache/spark/pull/11403, we introduced the
> function `canonicalized` for eliminating useless subqueries. We can simply
> replace the call of rule `EliminateSubqueryAliases` by the function
> `canonicalized`.
> After we changed the view resolution and management, the current reason why
> we keep `EliminateSubqueryAliases ` in optimizer becomes out-of-dated. Thus,
> we also should update the reason to `eager analysis of Dataset`.
