Subject [jira] [Commented] (AIRFLOW-43) Tasks never run in externally triggered DAGRun
Date Thu, 19 Jan 2017 21:46:26 GMT

    [ https://issues.apache.org/jira/browse/AIRFLOW-43?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15830660#comment-15830660

Feng Lu commented on AIRFLOW-43:
--------------------------------

The following works for us: 

1. Have the scheduler running and make sure it picks up the DAG file
2. unpause the DAG, e.g., airflow unpause <your_dag_id>
3. airflow trigger_dag dag_id. 

LMK how it runs for you.

>             Project: Apache Airflow
>          Issue Type: Bug
>    Affects Versions: Airflow 1.7.0
>         Environment: OSX, Python 2.7.5
>            Reporter: Chris Johnson
>            Assignee: Siddharth Anand
>            Priority: Critical

> I have a DAG which should only be run as needed (no schedule interval):
> dag = DAG(
>     dag_id='major_integ_cycle',
>     default_args=args,
>     schedule_interval=None,
> )
> I attempted to start this using `airflow trigger_dag NAME` but the tasks never run. 
The scheduler has noted the fact that itthe DAG was triggered: INFO - Created <DagRun major_integ_cycle
@ 2016-05-03 08:36:16.032474: manual__2016-05-03T08:36:16.032474, externally triggered: True>
> The tasks are currently very vanilla test cases, all look like this:
> task_mdc = op.BashOperator(
>     task_id='master_data_cycle',
>     bash_command='sleep 1',
>     dag=dag,
> )
> Have I misunderstood?  Or is not running a bug in this case?
