------------------------------------
Summary: Airflow workers should handle shutdowns gracefully
Key: AIRFLOW-1123
URL: https://issues.apache.org/jira/browse/AIRFLOW-1123
Project: Apache Airflow
Issue Type: New Feature
Components: worker
Reporter: Dan Davydov
Airflow should handle airflow worker shutdowns gracefully, i.e. it shouldn't
send failure emails, shouldn't trigger failure callbacks, and shouldn't
increment the retry number if a worker receives a signal to terminate. This
shutdown should still be communicated in the task logs/the UI though. This
change will probably require adding a new state for task instances, like KILLED
(which we can potentially reuse later for preemption if we choose to implement
it).
