[jira] [Created] (AIRFLOW-1537) SubDagOperator does not retry properly

Daniel Huang created AIRFLOW-1537:
-------------------------------------

             Summary: SubDagOperator does not retry properly
                 Key: AIRFLOW-1537
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1537
             Project: Apache Airflow
          Issue Type: Bug
          Components: backfill, scheduler, subdag
            Reporter: Daniel Huang


Since AIRFLOW-1124, we only backfill tasks with no state. While that makes sense for a backfill where we will use in combination with clear, it doesn't quite work in the context of a sub DAG that is set to retry.

I'd expect failed tasks to be rerun at least, but there can be some other side effects to doing that in other cases. [~artwr] mentioned this in https://github.com/apache/incubator-airflow/pull/2247/files#r112189191. Any thoughts on how to handle this [~bolke]?
