-----------------------------
Summary: Make trigger_dag & clear CLIs throw an error if 'shape'
of dag has changed since prior dagrun
Key: AIRFLOW-6524
URL: https://issues.apache.org/jira/browse/AIRFLOW-6524
Project: Apache Airflow
Issue Type: Improvement
Components: cli, scheduler
Affects Versions: 1.10.7
Reporter: t oo
if DagA had 20 tasks on first exec_date but then DagA code was changed and had
a different 15 or 25 tasks on second exec_date the scheduler will never run it.
The CLI's for trigger_dag & clear should throw error right away to make it
clear early that the Dagrun will never succeed.
