URL: https://github.com/apache/incubator-doris/issues/4316
**Describe the bug**
When user create no grouping materialized view on agg table, the job will be
executed successfully and the mv keys type is incorrect.
**To Reproduce**
1. create table
```
CREATE TABLE `test_sys_materialized_view_2_test_create_agg_mv_tb_agg` (
`k0` boolean NOT NULL COMMENT "",
`k1` tinyint(4) NOT NULL COMMENT "",
`k2` smallint(6) NOT NULL COMMENT "",
`k3` int(11) NOT NULL COMMENT "",
`k4` bigint(20) NOT NULL COMMENT "",
`k5` largeint(40) NOT NULL COMMENT "",
`k6` decimal(9, 3) NOT NULL COMMENT "",
`k7` char(5) NOT NULL COMMENT "",
`k8` date NOT NULL COMMENT "",
`k9` datetime NOT NULL COMMENT "",
`k10` varchar(20) NOT NULL COMMENT "",
`k11` double MAX NOT NULL COMMENT "",
`k12` float SUM NOT NULL COMMENT "",
`k13` hll HLL_UNION NOT NULL COMMENT "",
`k14` bitmap BITMAP_UNION NOT NULL COMMENT ""
) ENGINE=OLAP
AGGREGATE KEY(`k0`, `k1`, `k2`, `k3`, `k4`, `k5`, `k6`, `k7`, `k8`, `k9`,
`k10`)
COMMENT "OLAP"
DISTRIBUTED BY HASH(`k4`, `k5`) BUCKETS 10
PROPERTIES (
"replication_num" = "3",
"in_memory" = "false",
"storage_format" = "DEFAULT"
);
```
2. create mv
```
CREATE MATERIALIZED VIEW mv1 AS select k6, k7 from
test_sys_materialized_view_2_test_create_agg_mv_tb_agg
```
3.
**Expected behavior**
throw exception when creating mv.
error_msg: `The materialized view of aggregation table must has grouping
columns`
