Joe Schmid commented on AIRFLOW-1142:
-------------------------------------
I'm still seeing the issue even when running with v1-8-test + the PR for
AIRFLOW-1142: https://github.com/apache/incubator-airflow/pull/2260. In fact,
when running with --run-duration 30 I see the issue consistently.
I'm attaching two more logs: run3-task.log and run3-scheduler-stdout.log
> 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, run3-scheduler-stdout.log,
> run3-task.log, SubDAGOperatorTaskLog-DEBUG.txt, Test_Nested_SubDAG_0.png,

> 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.
