> Catch missing window specification error early
> ----------------------------------------------
>
> Key: SPARK-48740
> URL: https://issues.apache.org/jira/browse/SPARK-48740
> Project: Spark
> Issue Type: Task
> Components: Spark Core
> Affects Versions: 4.0.0
> Reporter: Amanda Liu
> Priority: Minor
> Labels: pull-request-available
>
> Before, aggregate queries containing a window function without a window
> specification (e.g. `PARTITION BY`) would return a non-descriptive internal
> error message:
> `org.apache.spark.sql.catalyst.analysis.UnresolvedException: [INTERNAL_ERROR]
> Invalid call to exprId on unresolved object SQLSTATE: XX000`
> This PR catches the user error early and returns a more accurate description
> of the issue:
> `Window specification <windowName> is not defined in the WINDOW clause.`
