Apache Airflow: Control over logging [Disable/Adjust logging level]

The logging functionality and its configuration will be changed in version 1.9 with this commit

I tried below work around and it seems to be working to set LOGGING_LEVEL outside of settings.py:

• Update settings.py:

  • Remove or comment line:
    LOGGING_LEVEL = logging.INFO

  • Add line:
    LOGGING_LEVEL = os.path.expanduser(conf.get('core', 'LOGGING_LEVEL'))

• Update airflow.cfg configuration file:

  • Add line under [core]: logging_level = WARN

  • Restart webserver and scheduler services

• Use environment vaiable AIRFLOW__CORE__LOGGING_LEVEL=WARN.

See the official docs for details.
