Marking task instances as successful can be done through the UI.

Clearing a task instance will no longer delete the task instance record.

The CLI command airflow clear -h has lots of options when it comes to clearing task instance.

Note that a confirmation window comes next andДЄllows you to see the set you are about to clear.

From the UI, you can clear (as in delete the status of) individual task instancesДЇrom the task instances dialog, while defining whether you want to includes the past/futureДЄnd the upstream/downstream dependencies.

Here are some of the ways you can unblock tasks: Whether the scheduler should look into triggering tasks for that run. It is important to keep in mind the DAG RunвЂ™s state too as it defines

When clearing a set of tasksвЂ™ state in hope of getting them to re-run,.

Your DAGвЂ™s schedule_interval, sequentially.

Subsequent DAG Runs are created by the scheduler process, based on.

The first DAG Run is created based on the minimum start_date for the.

Turning catchup off is great if your DAG Runs perform This behavior is great for atomicДatasets that can easily be split into periods.

If the dag.catchup value had been True instead, the scheduler would have created a DAG Run for eachД¬ompleted interval between -02 (but not yet one for, as that interval One will be created just after midnight on the morning of with an execution date of. In the example above, if the DAG is picked up by the scheduler daemon on at 6 AM, (or from theД¬ommand line), a single DAG Run will be created, with an execution_date of, and the next

To start a scheduler, simply run the command:ДЄ DAG Run is an object representing an instantiation of the DAG in time.Д®ach DAG may or may not have a schedule, which informs how DAG Runs areД¬reated. MesosExecutor, tasks are executed remotely. If it happens to be the LocalExecutor, tasks will beД®xecuted as subprocesses in the case of CeleryExecutor and The scheduler starts an instance of the executor specified in the yourДЄirflow.cfg. LetвЂ™s Repeat That The scheduler runs your job one schedule_interval AFTER the In other words, the job instance is started once the period it covers The run stamped will be trigger soon after T23:59. Note that if you run a DAG on a schedule_interval of one day,

It will use the configuration specified in To kick it off, all you need to do isД®xecute airflow scheduler. The Airflow scheduler is designed to run as a persistent service in anДЄirflow production environment. It monitors and stays in sync with a folder for all DAG objects it may contain,ДЄnd periodically (every minute or so) inspects active tasks to see whether Task instances whose dependencies have been met. The Airflow scheduler monitors all tasks and all DAGs, and triggers the
