# cosn

{{< stable >}}

Download [paimon-cosn-{{< version >}}.jar](https://repo.maven.apache.org/maven2/org/apache/paimon/paimon-cosn/{{< version >}}/paimon-oss-{{< version >}}.jar).

{{< /stable >}}

{{< unstable >}}

Download [paimon-cosn-{{< version >}}.jar](https://repository.apache.org/snapshots/org/apache/paimon/paimon-cosn/{{< version >}}/).

{{< /unstable >}}

{{< tabs "cosn" >}}

{{< tab "Flink" >}}

Put `paimon-cosn-{{< version >}}.jar` into `lib` directory of your Flink home, and create catalog:

```sql
CREATE CATALOG my_catalog WITH (
'type' = 'paimon',
'warehouse' = 'cosn://<bucket>/<path>',
'fs.cosn.bucket.endpoint_suffix' = 'cos.ap-beijing.myqcloud.com',
'fs.cosn.userinfo.secretId' = 'AKIDxxxx',
'fs.cosn.userinfo.secretKey' = 'yyy'
);
```

{{< /tab >}}

{{< tab "Spark" >}}

{{< hint info >}}
If you have already configured cosn access through Spark (Via Hadoop FileSystem), here you can skip the following configuration.
{{< /hint >}}

Place `paimon-cosn-{{< version >}}.jar` together with `paimon-spark-{{< version >}}.jar` under Spark's jars directory, and start like

```shell
spark-sql \
--conf spark.sql.catalog.paimon=org.apache.paimon.spark.SparkCatalog \
--conf spark.sql.catalog.paimon.warehouse=cosn://<bucket>/<path> \
--conf spark.sql.catalog.paimon.fs.cosn.bucket.endpoint_suffix=cos.ap-beijing.myqcloud.com \
--conf spark.sql.catalog.paimon.fs.cosn.userinfo.secretId=AKIDxxxx \
--conf spark.sql.catalog.paimon.fs.cosn.userinfo.secretKey=yyy
```

{{< /tab >}}

{{< tab "Hive" >}}

{{< hint info >}}
If you have already configured cosn access through Hive (Via Hadoop FileSystem), here you can skip the following configuration.
{{< /hint >}}

NOTE: You need to ensure that Hive metastore can access `cosn`

Place `paimon-cosn-{{< version >}}.jar` together with `paimon-hive-connector-{{< version >}}.jar` under Hive's auxlib directory, and start like

```sql
SET paimon.fs.cosn.bucket.endpoint_suffix=cos.ap-beijing.myqcloud.com;
SET paimon.fs.cosn.userinfo.secretId=AKIDxxxx;
SET paimon.fs.cosn.userinfo.secretKey=yyy;
```

And read table from hive metastore, table can be created by Flink or Spark, see [Catalog with Hive Metastore]({{< ref "how-to/creating-catalogs" >}})
```sql
SELECT * FROM test_table;
SELECT COUNT(1) FROM test_table;
```
