Marc Weil commented on AIRFLOW-1026:
I'm having the same issue as well, and sadly this will prevent me from
upgrading to 1.8.0 until it's resolved.

> Key: AIRFLOW-1026
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1026
> Project: Apache Airflow
> Issue Type: Bug
> Components: configuration
>Affects Versions: Airflow 1.8
>Reporter: Harish Singh
>Priority: Critical
> Fix For: Airflow 1.8

>
> sql_alchemy_conn_cmd = python ./pipeline/dags/configure.py
> I am expectiing configure.py to be invoked.
> But it just throws:
> "cannot use sqlite with the LocalExecutor"
> The connection string that my script "configure.py" would return is something
> like this:
> mysql+mysqldb://username:**@mysqlhostname:3306/airflowdbname
> But after debugging, I found that, my script is not getting invoked at all.
> This is my airflow.cfg:
> executor = LocalExecutor
> sql_alchemy_conn_cmd = python ./pipeline/dags/configure.py
> sql_alchemy_pool_size = 5
> sql_alchemy_pool_recycle = 3600
> I tried not using the script and directly hardcoding the conn_url
> sql_alchemy_conn =
> mysql+mysqldb://username:**@mysqlhostname:3306/airflowdbname
> It works.
> But there is a regression bug if somebody wants to use "sql_alchemy_conn_cmd"
