>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-3357
>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: scheduler
>    Affects Versions: 1.10.0, 1.10.1
>            Reporter: Victor Villas Bôas Chaves
>            Priority: Major
>
> Having a blank Airflow install, if you try to manually run one of the example DAGs no tasks are going to get queued or executed. They're going to stay with state null.
> Steps to reproduce on a new airflow:
>  # Entered the UI, turned on the example_bash_operator, manually triggered the example_bash_operator, 6 tasks went to None state, nothing gets scheduled
>  # Rebooted the scheduler (with debug logging on). Nothing gets scheduled.
>  # Create a mytutorial.py in the dag folder with code from tutorial.py but DAG name changed, everything starts getting scheduled.
> A debug view of the logs is here: [https://gist.github.com/tomfaulhaber/4e72ed0884c9580c606e02e4b745ddff]
