-----------------------------------
Summary: Tasks are not skipping correctly
Key: AIRFLOW-872
URL: https://issues.apache.org/jira/browse/AIRFLOW-872
Project: Apache Airflow
Issue Type: Bug
Components: cli, DagRun, webserver
Affects Versions: Airflow 1.8
Environment: docker-compose using docker-compose-LocalExecutor.yml on
this fork/branch https://github.com/fdm1/docker-airflow/tree/v1-8-not-skipping
Reporter: Frank Massi

When using the BranchPythonOperator or ShortCircuitOperator to make Dags
idempotent, if running the Dag after a successful DagRun and clearing the
initial task, the second task skips and then the Dag enters a failed state, as
opposed to skipping all remaining tasks and marking the Dag successful.
Steps to reproduce are outlined here:
https://github.com/fdm1/docker-airflow/blob/v1-8-not-skipping/dags/test_clear_bug.py#L4-L9
In 1.7.1.3, the tasks do skip correctly, so this appears to be a new bug.
