Troubleshooting and limitations


Error message: 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;

Error message: ModuleNotFoundError: No module named 'databricks.feature_store'

This error occurs when the Feature Store Python client is not installed on the Databricks Runtime you are using.

The Feature Store Python client is available on PyPI, and can be installed with:

%pip install databricks-feature-store


  1. Feature Store does not support deleting individual features from a feature table.
