Setting up a snowflake catalog via spark config next to unity catalog

[Laurens]

Im trying to set up a connection to Iceberg on S3 via Snowflake as described https://medium.com/snowflake/how-to-integrate-databricks-with-snowflake-managed-iceberg-tables-7a889... and https://docs.snowflake.com/en/user-guide/tables-iceberg-catalog

On a cluster with Unity Catalog disabled this works fine and I can read from the tables without connecting to a snowflake warehouse. When Unity Catalog is enabled however, the `snowflake_catalog` is nowhere to be found.

Is there a way to setup a catalog via Spark config like described above while using Unity Catalog?

Thanks in advance!

Hi Kaniz,

Thanks for your elaborate reply! The iceberg data that we have to interact with uses Snowflake as catalog, not glue. Can we also use a catalog integration with Snowflake?

Thanks!

Hi @Retired_mod ,

We've been working on setting up Glue as catalog, which is working fine so far. However, Glue takes place of the hive_metastore, which appears to be a legacy way of setting this up. Is the way proposed here the recommended way to set it up, or is there a more "unity catalog" way of setting it up? https://docs.databricks.com/en/archive/external-metastores/aws-glue-metastore.html

Thanks in advance,

Laurens
