> Airflow should track Celery task ID
> -----------------------------------
>
> Key: AIRFLOW-2307
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2307
> Project: Apache Airflow
> Issue Type: Improvement
> Components: scheduler
> Affects Versions: 1.9.0
> Reporter: John Arnold
> Priority: Minor
>
> For celery executor, airflow keeps the AsyncResult in memory for the duration
> of the task, then deletes when task completes (success or fail).
> This can make troubleshooting failed tasks hard – trying to figure out which
> task instance is which "celery task" in Flower, etc.
> It would be a lot easier if there was a "Task Instance id" that could be
> populated with the AsyncResult.id for celery, or otherwise a UID for other
> executors.
