-------------------------------
Summary: 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`.
