------------------------------------
Summary: Tasks rejected by workers get stuck in QUEUED
Key: AIRFLOW-1143
URL: https://issues.apache.org/jira/browse/AIRFLOW-1143
Project: Apache Airflow
Issue Type: Bug
Components: scheduler
Reporter: Dan Davydov
If the scheduler schedules a task that is sent to a worker that then rejects
the task (e.g. because one of the dependencies of the tasks became bad, like
the pool became full), the task will be stuck in the QUEUED state.
Restarting the scheduler fixes this because it cleans up orphans, but we
shouldn't have to restart the scheduler to fix these problems (the missing job
heartbeats should make the scheduler requeue the task).
