Seems the primiary key can't be derived from the iceberg's HiveCatalog even
though you have defined it using Hive Cli .
1. you can define with the following using Flink SQL
```
CREATE TABLE ods_data_1_1 (
xxx,
xxx,
PRIMARY KEY(`id`) NOT ENFORCED
) WITH (
'connector'='iceberg',
'catalog-name'='hive_prod',
'catalog-database'='default',
'catalog-table'='ods_data_1_1',
'uri'='hdfs://nn-1:8020/user/hive/warehouse/',
'warehouse'='hdfs://nn:8020/path/to/warehouse'
);
```
Note: it won't create a table, it's just a mapping to the table crated
before in Hive
Then write the data using the sql normally.
2. You can use Flink DDL to create the table, the Hive should have the
ability to read the table. Have you ever followed the document [enable Iceberg
support]
(https://iceberg.apache.org/docs/latest/hive/#enabling-iceberg-support-in-hive)?
