Post-Upgrade Steps for Airflow

Use these steps:

1. Run configure.sh -R to update the airflow.cfg file:

   /opt/mapr/server/configure.sh -R

2. For upgrades from an older version of Airflow to a newer version, run the Airflow database initialization tool to create the airflow.cfg file:

   airflow db init

3. Migrate any custom configuration settings (especially database-related settings) into the <airflow_home>/conf/ directory. For example, if MySQL is used as the database, install the mysqlclient by using the following steps:
   1. Run .<airflow_home>/build/env/bin/activate
   2. Run pip install mysqlclient==2.1.1
   3. Run deactivate
4. For upgrades from an older version of Airflow to a newer version, run the Airflow database upgrade tool:

   airflow db upgrade 

   For more information about the upgrade tool, see Reference for Database Migrations in the Apache Airflow documentation.
5. Start the airflow-scheduler and airflow-webserver services:

   maprcli node services -nodes <hostname> -name airflow-scheduler -action start
   maprcli node services -nodes <hostname> -name airflow-webserver -action start

6. Optional: If using the default SequentialExecutor, create a user. For example:

   airflow users create --username any_user --firstname any_user --lastname any_user -p any_user --role Admin --email admin@example.org
