-------------------------------
see if https://github.com/apache/airflow/pull/6954 helps
> Tasks get stuck in the "removed" state
> --------------------------------------
>
> Key: AIRFLOW-7116
> URL: https://issues.apache.org/jira/browse/AIRFLOW-7116
> Project: Apache Airflow
> Issue Type: Bug
> Components: DAG
> Affects Versions: 1.10.9
> Environment: Mac OS Catalina
> Airflow 1.10.9
> Airflow running locally using out of box sqlite database
> Reporter: Chris
> Priority: Major
> Labels: DAG, local, sqlite, tasks
> Attachments: Untitled.png
>
>
> This appears to be a regression of:
>
> https://issues.apache.org/jira/browse/AIRFLOW-1460
>
> Repro steps:
>
> # Configure Dag to run within context manager via "with" keyword.
> # Comment out one or more tasks within a Dag.
> # Refresh Dag.
> # Trigger Dag.
> # Notice the tasks are removed from the dag and the dag runs the
> non-commented task(s) successfully.
> # Uncomment the tasks that were commented before.
> # refresh dag.
> # trigger dag.
>
> Observed results:
> * The tree view of the dag does not update, showing the re-added tasks.
> * After Triggering the Dag, (only the task(s) that was/were tested while the
> others were commented out appears in the Graph View)
> * On the graph view, the dag's uncommented tasks only appear after
> restarting Airflow Server/Scheduler.
> * Even though the Airflow server was restarted, and although the dag now
> shows all the tasks in both Tree view and Graph view, the dag, when
> triggered, only runs the task(s) that were previously not commented.
> * Note that the tasks when hovering mouse over them in Graph View, show
> "State" as "removed".
