For parameters not configured via environment variables, the 'DEFAULT' The Databricks Python SDK reads these values from two locations - first from environment variables If this environment variable is not configured, Databricks Connect will now look for connection SPARK_REMOTE = 'sc://:443/ token= x-databricks-cluster-id=' Read more about spark connect connection string. If configured, the SPARK_REMOTE environment variable must contain the spark connect connection getOrCreate ()įirst, the SPARK_REMOTE environment variable is used if it's configured. Parameters are picked up from the environment.
