------------------------------------
Resolution: Not A Problem
> Fail when using aliased column of a aliased table from a subquery
> -----------------------------------------------------------------
>
> Key: SPARK-21486
> URL: https://issues.apache.org/jira/browse/SPARK-21486
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.0, 2.1.1, 2.2.0
> Reporter: Miguel Angel Fernandez Diaz
>
> SparkSQL cannot resolve a qualified column when using the column alias and
> the table alias from a subquery.
> Example:
> {code:sql}
> SELECT a21.ta FROM (SELECT tip_amount as ta FROM yellow a21)
> {code}
> Error:
> {code}
> org.apache.spark.sql.AnalysisException: cannot resolve '`a21.ta`' given input
> columns: [ta]; line 1 pos 7;
> 'Project ['a21.ta]
> +- Project [tip_amount#505 AS ta#489]
> +- SubqueryAlias a21
