Upgrade to Airflow 1.10 - _mysql_exceptions.OperationalError: (1054, "Unknown column 'task_instance.executor_config' in 'field list'")

Question

I just updated to Airflow 1.10 following the instructions here: https://medium.com/datareply/apache-airflow-1-10-0-released-highlights-6bbe7a37a8e1

When I click on a DAG in the web GUI I get the following error: _mysql_exceptions.OperationalError: (1054, "Unknown column 'task_instance.executor_config' in 'field list'")

Seemingly upgrading requires changes to the database. Is there a command to alter existing tables? I didn't find anything on this in the Updating Airflow docs.

Answer 1

airflow upgradedb won't work if you upgrade from airflow 1.8 directly to 1.10, you should upgrade to 1.9 first, use airflow upgradedb and then do the same process from 1.9 to 1.10.

Answer 2

OK, found out that there is a command airflow upgradedb that fixes this and should be run after upgrading from Airflow 1.9 to 1.10.
