             Summary: The "from airflow import settings" is used far too often
                 Key: AIRFLOW-6010
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-6010
             Project: Apache Airflow
          Issue Type: Sub-task
          Components: core
    Affects Versions: 2.0.0
            Reporter: Jarek Potiuk


In many places "from airflow import settings" is used only to get the latest set value of one or few settings or when single method from settings is going to be called.

Settings loads a lot of dependencies on its own and having it imported at the top of the file often causes many transitive/implicit dependencies which might cause circular imports.

Therefore in many places the settings should be imported as local imports. This causes lasy-loading of settings in case of tests but also it makes sure that even if the values in settings are overridden by some other initialisation, we will always use latest version of settings.
