问题
I have a DAG 'abc' scheduled to run every day at 7 AM CST and there is task 'xyz' in that DAG.
For some reason, I do not want to run one of the tasks 'xyz' for tomorrow's instance.
How can I skip that particular task instance?
- I do not want to make any changes to code as I do not have access to Prod code and the task is in Prod environment now.
- Is there any way to do that using command line ?
Appreciate any help on this.

You can mark the unwanted tasks as succeeded using the run command. The tasks marked as succeeded will not be run anymore.
Assume, there is a DAG with ID a_dag and three tasks with IDs dummy1, dummy2, dummy3. We want to skipp the dummy3 task from the next DAG run.
First, we get the next execution date:
$ airflow next_execution a_dag
2020-06-12T21:00:00+00:00
Then we mark dummy3 as succeeded for this execution date:
$ airflow run -fAIim a_dag dummy3 '2020-06-12T21:00:00+00:00'
To be sure, we can check the task state. For the skipped task it will be success:
$ airflow task_state a_dag dummy3 '2020-06-12T21:00:00+00:00'
...
success
For the rest of the tasks the state will be None:
$ airflow task_state a_dag dummy1 '2020-06-12T21:00:00+00:00'
...
None
