我生成了一个hive catalog, 查询数据没有问题，但是insert时报如下错误，如何解决？
'hive_krb' is not allowed in 'NativeInsertStmt'
mysql> insert into hive_krb.`default`.employee values(4,'emp4',332,'ggsssddd');
ERROR 1105 (HY000): errCode = 2, detailMessage = External catalog 'hive_krb' is not allowed in 'NativeInsertStmt'
我也看了优化器，配置是正常的：
mysql> show variables like "%planner%";
+-------------------------------------------+-------+---------------+---------+
| Variable_name | Value | Default_Value | Changed |
+-------------------------------------------+-------+---------------+---------+
| enable_fallback_to_original_planner | true | true | 0 |
| enable_variant_access_in_original_planner | false | false | 0 |
| experimental_enable_nereids_planner | true | true | 0 |
