[jira] [Created] (SPARK-56035) Introduce `AggregateValidator` for single-pass resolver `Aggregate` validation

---------------------------------------

             Summary: Introduce `AggregateValidator` for single-pass resolver `Aggregate` validation
                 Key: SPARK-56035
                 URL: https://issues.apache.org/jira/browse/SPARK-56035
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 4.1.1
            Reporter: Mihailo Aleksic


Right now
```
SELECT col1 + rand() FROM VALUES(1) GROUP BY ALL
```
fails with `MISSING_AGGREGATION` in the single-pass resolver because we can't match grouping and aggregate expressions since `semanticEquals` requires both expressions to be deterministic but we do the validation before `PulloutNonDeterministic` call.
