Mas created AIRFLOW-1641:
----------------------------
Summary: Task gets stuck in queued state
Key: AIRFLOW-1641
URL: https://issues.apache.org/jira/browse/AIRFLOW-1641
Project: Apache Airflow
Issue Type: Bug
Components: scheduler
Affects Versions: 1.8.0
Environment: Linux
Reporter: Mas
Hello,
I have one dag with ~20 tasks.
The dags runs daily and some tasks can sometime last for hours, depending on
the processed data behind.
There are some interactions with AWS and a remote DB.
I only use LocalExecutor.
What this issue is about, is the fact that sometime (randomly, and without any
clear reason) one of the tasks (here also, it is random) gets stuck in "queued"
state and never starts running.
The manual workaround is to restart the task manually by clearing it.
Does anyone have ideas about the issue behind, and how to avoid it for the
future?
Thanks in advance for your help.
PS: other people are facing the same behaviour:
