Bolke de Bruin commented on AIRFLOW-1142:
-----------------------------------------
- You UI seems to indicate two successful runs. Can you explain why the other
two runs seem to succeed?
- Can you rerun with debug logging enabled? I have too much missing information
At the moment I cannot confirm this with LocalExecutor and by triggering a
single dag.
> SubDAG Tasks Not Executed Even Though All Dependencies Met

> Key: AIRFLOW-1142
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1142
> Project: Apache Airflow
> Issue Type: Bug
> Components: subdag
> Affects Versions: 1.8.1
> Environment: 1.8.1rc1+incubating, Celery
> Reporter: Joe Schmid
> Priority: Blocker
> Attachments: 2017-04-24T23-20-38-776547, Test_Nested_SubDAG_0.png,
> Test_Nested_SubDAG_1-Zoomed.png, test_nested_subdag.py
>
>
> Testing on 1.8.1rc1, we noticed that tasks in subdags were not getting
> executed even though all dependencies had been met.
> We were able to create a simple test DAG that re-creates the issue. Attached
> is a test DAG, the log file of the subdag operator that shows it fails to run
> even though dependencies are met, and screenshots of what the UI looks like.
> This is definitely a regression as we have many similarly constructed DAGs
> that have been running successfully on a pre-v1.8 version (a fork of
> 1.7.1.3+master) for some time.
