dataageek opened a new issue, #6310:
URL: https://github.com/apache/gravitino/issues/6310
### Version
main branch
### Describe what's wrong
I have multiple catalogs created using the Iceberg JDBC catalog. When I
attempt to consume these catalogs via the Gravitino REST server (using the REST
catalog through Spark), the implementation always defaults to using jdbc as the
catalog name instead of the catalog name specified in the Spark configuration.
For example, when running the following command:
```
./spark-sql \
--conf
spark.sql.catalog.iceberg_jdbc_catalog=org.apache.iceberg.spark.SparkCatalog \
--conf
spark.sql.catalog.iceberg_jdbc_catalog.warehouse="/mnt/c/iceberg-warehouse" \
--conf spark.sql.catalog.iceberg_jdbc_catalog.type=rest \
--conf
spark.sql.catalog.iceberg_jdbc_catalog.uri=http://127.0.0.1:9991/iceberg \
--conf
spark.sql.extensions=org.apache.iceberg.spark.extensions.IcebergSparkSessionExtensions
```
I expect Spark to use the iceberg_jdbc_catalog catalog, as specified in the
configuration. However, the Gravitino REST server implementation instead looks
for a catalog named jdbc.
Although I can override this behavior using the catalog-backend-name
property in gravitino.conf, I would prefer a dynamic mechanism that fetches the
catalog name from the Spark configuration directly.
