James Meickle updated AIRFLOW-2178: ----------------------------------- Attachment: log.txt > Scheduler can't get past SLA check if SMTP settings are incorrect > ----------------------------------------------------------------- > > Key: AIRFLOW-2178 > URL: https://issues.apache.org/jira/browse/AIRFLOW-2178 > Project: Apache Airflow > Issue Type: Bug > Components: scheduler > Affects Versions: 1.9.0 > Environment: 16.04 > Reporter: James Meickle > Priority: Major > Attachments: log.txt > > > After testing Airflow for a while in staging, I provisioned our prod cluster > and enabled the first DAG on it. The "backfill" for this DAG performed just > fine, so I assumed everything was working and left it over the weekend. > However, when the last "backfill" period completed and the scheduler > transitioned to the most recent execution date, it began failing in the > `manage_slas` method. Due to a configuration difference, SMTP was timing out > in production, preventing the SLA check from ever completing; this both > blocked SLA notifications, as well as prevented further tasks in this DAG > from ever getting scheduled. > As an operator, I would expect AIrflow to treat scheduling tasks as a > higher-priority concern, and to do so even f the SLA feature fails to work. I > would also expect Airflow to notify me in the web UI that email sending is > not currently working. > > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
