dud created AIRFLOW-106:
---------------------------
Summary: email_on_failure doesn't being triggered
Key: AIRFLOW-106
URL: https://issues.apache.org/jira/browse/AIRFLOW-106
Project: Apache Airflow
Issue Type: Bug
Environment: Latest version from Git
Reporter: dud
Hello.
I created the following workflow :
{code}
from airflow import DAG
from airflow.operators import PythonOperator
from datetime import datetime, timedelta
from airflow.models import Variable
from time import sleep
default_args = {
'depends_on_past': False,
'start_date': datetime(2016, 5, 11, 15, 20),
'email': <my email>
'email_on_failure': True,
'email_on_retry': False,
'retries': 1,
'retry_delay': timedelta(minutes=2),
'end_date': datetime(2016, 5, 11, 16, 00),
}
PARENT_DAG_NAME = 'test'
dag = DAG(PARENT_DAG_NAME, default_args=default_args,
schedule_interval=timedelta(minutes=10))
def sleep1_function(**kwargs):
sleep(90)
return Variable.get('test_var')
sleep1 = PythonOperator(
task_id='sleep1',
python_callable=sleep1_function,
dag=dag)
{code}
I forgot to declare test_var so when this DAG launched it failed quickly.
However no failure email was ever sent. Clearing the failed task to make it
rerun doesn't trigger any email.
Here is the logs :

{code}
In the DAG Runs page, the workflow is set as failed. In hte taks instance page,
it is set as up_for_retry but no new run is ever scheduled.
I tried incrementing the retires parameter, but nothing different happens,
Airflow ever retries after the first run.
