Marty Woodlee commented on AIRFLOW-1026:
I am having the same issue.
I believe this is happening because the Python {{ConfigParser}} behaves in an
additive/"merging" fashion when multiple configs are read, and at
https://github.com/apache/incubator-airflow/blob/1.8.0/airflow/configuration.py#L524,
the built-in {{DEFAULT_CONFIG}} is read before the user's _actual_ config is
loaded up at
https://github.com/apache/incubator-airflow/blob/1.8.0/airflow/configuration.py#L784.
Since the default config _does_ contain a {{sql_alchemy_conn}} entry (which
points to a local SQLite DB), the config code never tries to evaluate
{{sql_alchemy_conn_cmd}} since doing so takes lower precedence (see
https://github.com/apache/incubator-airflow/blob/1.8.0/airflow/configuration.py#L592-L605).
At first glance I'm not sure any of the {{\_cmd}} options have _ever_ worked?
My first instinct is that probably the {{DEFAULT_CONFIG}} should only ever get
read if it is known that there is no user-supplied config yet. May need
thought, though, if anyone is actually reliant upon that "fall-back" behavior?
(Let's hope not.)
