Database recommender_system does not exist in the Hive metastore.
A feature table is stored as a Delta table. The database is specified by the table name prefix, so a feature table recommender_system.customer_features will be stored in the recommender_system database.
To create the database, run:
%sql CREATE DATABASE IF NOT EXISTS recommender_system;
ModuleNotFoundError: No module named 'databricks.feature_store'
This error occurs when the Feature Store Python client is not available on the Databricks Runtime you are using. For a list of supported Databricks Runtime versions, see Requirements.
