Apache Spark reassigned AIRFLOW-2965:
-------------------------------------
Assignee: Holden Karau's magical unicorn (was: Xiaodong DENG)
> Add CLI command to find the next dag run.
> -----------------------------------------
>
> Key: AIRFLOW-2965
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2965
> Project: Apache Airflow
> Issue Type: Task
> Reporter: jack
> Assignee: Holden Karau's magical unicorn
> Priority: Minor
> Fix For: 1.10.1
>
>
> I have a dag with the following properties:
> {code:java}
> dag = DAG(
> dag_id='mydag',
> default_args=args,
> schedule_interval='0 1 * * *',
> max_active_runs=1,
> catchup=False){code}
>
>
> This runs great.
> Last run is: 2018-08-26 01:00 (start date is 2018-08-27 01:00)
>
> Now it's 2018-08-27 17:55 I decided to change my dag to:
>
> {code:java}
> dag = DAG(
> dag_id='mydag',
> default_args=args,
> schedule_interval='0 23 * * *',
> max_active_runs=1,
> catchup=False){code}
>
> Now, I have no idea when will be the next dag run.
> Will it be today at 23:00? I can't be sure when the cycle is complete. I'm
> not even sure that this change will do what I wish.
> I'm sure you guys are expert and you can answer this question but most of us
> wouldn't know.
>
> The scheduler has the knowledge when the dag is available for running. All
> I'm asking is to take that knowledge and create a CLI command that I will
> give the dag_id and it will tell me the next date/hour which my dag will be
> runnable.
