Hi Folks!There is a bug on current Master that might be related to a commit on April 4. I need to confirm with the committer. If so, then we have another blocker bug on the release candidate. https://issues.apache.org/jira/browse/AIRFLOW-106
In a nutshell:Task retries, on_failure callback, and email_on_failure are not honored if the first task in a DAG fails. The bug presents itself when task retries are enabled and the first task in a DAG run fails one time. If this happens, then retries are not honored on the task that only failed one time. The task will be left in a permanent "UP_FOR_RETRY" state. As a result, failure hooks will not be executed for that failed task including email notification that the task failed. -s
