--------------------------------------------------
Summary: Scheduler doesn't work on example DAGs unless there's
some dag file to process
Key: AIRFLOW-3357
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
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:
