#### Example: Hive Metastore Catalog

**Server Configuration (`server.yaml`):**
```yaml
datalake.format: iceberg
datalake.iceberg.type: hive
datalake.iceberg.uri: thrift://<hive-metastore-host>:9083
datalake.iceberg.warehouse: hdfs:///path/to/iceberg/warehouse
```

**Required Dependencies:**

| Location | JARs |
|----------|------|
| `${FLUSS_HOME}/plugins/iceberg/` | `iceberg-hive-metastore-1.10.1.jar` |
| `${FLINK_HOME}/lib/` (for tiering) | `iceberg-hive-metastore-1.10.1.jar`, Hive client JARs (`hive-metastore-*.jar`, `libfb303-*.jar`) |

```bash
# Download Iceberg Hive Metastore JAR
wget https://repo1.maven.org/maven2/org/apache/iceberg/iceberg-hive-metastore/1.10.1/iceberg-hive-metastore-1.10.1.jar \
-P ${FLUSS_HOME}/plugins/iceberg/
```

**Start Tiering Service:**
```bash
${FLINK_HOME}/bin/flink run /path/to/fluss-flink-tiering-$FLUSS_VERSION$.jar \
--fluss.bootstrap.servers localhost:9123 \
--datalake.format iceberg \
--datalake.iceberg.type hive \
--datalake.iceberg.uri thrift://hive-metastore:9083 \
--datalake.iceberg.warehouse hdfs:///iceberg/warehouse
```

**Quick Troubleshooting:**

| Error | Fix |
|-------|-----|
| `NoClassDefFoundError: IMetaStoreClient` | Add `hive-metastore-*.jar` to classpath |
| `Could not connect to meta store` | Verify HMS URI and network connectivity |
