>                 Key: AIRFLOW-3486
>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-3486
>             Project: Apache Airflow
>          Issue Type: Bug
>    Affects Versions: 1.10.1
>            Reporter: Nik Bates-Haus
>            Priority: Major
>         Attachments: lineage-backend-atlas.patch

> lineage.rst says to configure lineage as:
> {code:java}
> [lineage]
> backend = airflow.lineage.backend.atlas
> [atlas]
> username = my_username
> password = my_password
> host = host
> port = 21000
> {code}
> but this fails, because {{airflow.lineage.backend.atlas}} is a module, not a class, and therefore cannot be loaded by {{import_string}}.
> Specifying  {{airflow.lineage.backend.atlas.AtlasBackend}} instead loads the backend, but is unable to send to it because it tries to use the class, rather than an instance of the class, as the backend.
> I have a fix in the attached patch, including:
>  * Documentation fix
>  * Fix for {{_get_backend()}}
>  * Test to ensure that the backend can be loaded and used
