----------------------------------
Summary: Duplicate operator task ids raise inappropriate error
message
Key: AIRFLOW-4726
URL: https://issues.apache.org/jira/browse/AIRFLOW-4726
Project: Apache Airflow
Issue Type: Improvement
Components: DAG
Affects Versions: 1.10.3
Reporter: Yu Kodama
Assignee: Yu Kodama
Attachments: airflow_admin.png, duplicate_operators.py
When there are duplicate operator task ids, it raises `Broken DAG: Cycle
detected in DAG. Faulty task: foo to foo`.
This error message is ambiguous, so I suggest that `Broken DAG: duplicate task
ids. ~~~` is better.
I examined this case on my local environment (Airflow version: 1.10.3).
DAG script and error messages are on Attachment.
(I changed [https://airflow.apache.org/tutorial.html] a little to make this DAG
script.)
