URL: https://github.com/apache/superset/issues/22267
Hi Team
I have installed superset with **docker** container, logged in to superset.
**I wanted to connect to Azure Databricks**. I have followed the below steps.
1. I have created "requirements-local.txt" file in /superset/docker/ folder.
2. Added "databricks-dbapi[hive,odbc,sqlalchemy]" in
"requirements-local.txt" file.
3. Ran "docker-compose build --force-rm" command to build.
4. Ram "docker-compose -f docker-compose-non-dev.yml up" command to run the
docker.
5. Superset is up and running and able to login.
#### How to reproduce the bug
1. Go to Data -> "Connect a database"
2. Select "Databricks SQL Endpoint" in "SUPPORTED DATABASES" dropdown .
3. Provide
"databricks+pyhive://token:{access_token}@{server_hostname}:{port}/{database_name}"
URL details from Databricks, for "SQLALCHEMY URI"
4. Provide "{"connect_args": {"http_path": "sql/protocolv1/o/****"}}" with
Http Path, in ADVANCED > Other > ENGINE PARAMETERS.
5. Click on "TEST CONNECTION"
6. Below ERROR occurred
ERROR:
