> Consider the following query: `SELECT (SUM(col1) OVER(unspecified_window) /
> 1) FROM VALUES (1)`. Currently the resolution produces
> `org.apache.spark.sql.catalyst.analysis.UnresolvedException: [INTERNAL_ERROR]
> Invalid call to dataType on unresolved object SQLSTATE: XX000`, which is
> confusing. We need to change it to `ExtendedAnalysisException:
> [MISSING_WINDOW_SPECIFICATION]`
