I have added a minio data source. There are some tables in iceberg format on this minio. I use hive metastore to manage the metadata of iceberg format tables. How can I format these tables in dremio-oss? Now the following error is reported: This folder does not contain a filesystem-based Iceberg table. If the table in this folder is managed via a catalog such as Hive, Glue, or Nessie, please use a data source configured for that catalog to connect to this table.

If your table is created and managed by a metastore then you need to add the same metastore to Dremio instead of getting to the table via S3/Minio.  
Metastore has the information about current table snapshot and table operations should be performed via metastore otherwise you run into the risk of ruining table’s consistency.

Is there a place to configure metastore in dremio-oss?
