### Spark SQL

 **Schema**

 _empty_

 **Query**

 ```sql
 CREATE VIEW group-by_050 AS
 SELECT count(*)
 FROM VALUES (named_struct('b', array(map(1, 2, 2, 3), map(1, 3)))), (named_struct('b', array(map(2, 3), map(1, 3)))), (named_struct('b', array(map(2, 3, 1, 2), map(1, 3)))) as t(a)
 GROUP BY a;
 ```

 **Expected result**

 ```
 2
 1
 ```

 ### Feldera SQL (translated)

 **Schema**

 _empty_

 **Query**

 ```sql
 CREATE VIEW "group-by_050" AS
 SELECT COUNT(*)
 FROM (
   VALUES
     (CAST(ROW(ARRAY[MAP[1, 2, 2, 3], MAP[1, 3]]) AS ROW(b MAP<INT, INT> ARRAY))),
     (CAST(ROW(ARRAY[MAP[2, 3], MAP[1, 3]]) AS ROW(b MAP<INT, INT> ARRAY))),
     (CAST(ROW(ARRAY[MAP[2, 3, 1, 2], MAP[1, 3]]) AS ROW(b MAP<INT, INT> ARRAY)))
 ) AS t(a)
 GROUP BY a
 ```

 ### Status

 | Phase | Status |
 |---|---|
 | Translation | `success` |
 | Compilation | `ok` |
 | Execution   | `error` |
 | Match       | `False` |

 **Detail:** row count mismatch: feldera=0 spark=2
