Research direction

Start by reproducing the shown databricks.sql.connect call and inspecting the connector's SSL/TLS configuration and certificate-verification path. Done means identifying why the warehouse certificate fails verification and documenting or testing a supported connection fix; the issue names no repository file or test.

Written by the indexing model from the issue text.

Description

Getting the following error when trying to connect to our warehouse:

from databricks import sql
your_token = '<token>'

connection = sql.connect(
  server_hostname="<>cloud.databricks.com",
  http_path="/sql/1.0/warehouses/<>",
  access_token=your_token
)

MaxRetryError: HTTPSConnectionPool(host='<>.cloud.databricks.com', port=443): Max retries exceeded with url: /sql/1.0/warehouses/<> (Caused by SSLError(SSLError("bad handshake: Error([('SSL routines', 'tls_process_server_certificate', 'certificate verify failed')])")))

We have tried:

connection = sql.connect(
  server_hostname="<>.cloud.databricks.com",
  http_path="/sql/1.0/warehouses/<>",
  access_token=your_token,
  _tls_no_verify=True)

and

connection = sql.connect(
  server_hostname="<>.cloud.databricks.com",
  http_path="/sql/1.0/warehouses/<>",
  access_token=your_token,
  _enable_ssl=False)
