> A sort after Aggregate can fail to resolve if it contains nested fields. For example
> {code:java}
> SELECT c.x, SUM(c.y)
> FROM VALUES NAMED_STRUCT('x', 'A', 'y', 1), NAMED_STRUCT('x', 'A', 'y', 2) AS t(c)
> GROUP BY c.x
> ORDER BY c.x
> {code}
> Error:
> {code}
> org.apache.spark.sql.AnalysisException: cannot resolve 'c.x' given input columns: [sum(c.y), x]; line 5 pos 9;
> 'Sort ['c.x ASC NULLS FIRST], true
> +- Aggregate [c#0.x], [c#0.x AS x#2, sum(c#0.y) AS sum(c.y)#5L]
>    +- SubqueryAlias t
>       +- LocalRelation [c#0]
