-----------------------------------
Summary: Scheduler get stuck using param -r or -n
Key: AIRFLOW-1550
URL: https://issues.apache.org/jira/browse/AIRFLOW-1550
Project: Apache Airflow
Issue Type: Bug
Reporter: yuanyifang
we use airflow scheduler -r or -n param in our project to make sure no task in
queue status which will cause no more task got scheduled. But we encountered
another problem. We found no task in any dag in running state except a
hdfssensor and the scheduler did not stop as we expected.
we think this is because scheduler waiting for all the running task finish and
than quit running. But the hdfssensor will waiting for a file ready for a long
time. so the scheduler will not quit and not schedu other task.
