jack created AIRFLOW-4927: ----------------------------- Summary: Airflow task stuck in Scheduled mode due to pool not existed Key: AIRFLOW-4927 URL: https://issues.apache.org/jira/browse/AIRFLOW-4927 Project: Apache Airflow Issue Type: Bug Components: core Affects Versions: 1.10.4 Reporter: jack
When operator uses pool like the scheduler schedule the task only when slot is available. We encounter a case where one of our developers did: {code:java} op = CustomOperator( task_id='id', conn_id='con', pool='file_default'){code} However file_default was not defined in pools. It took us hours to find that the pool does not exist. No error nor any indication was given. Airflow should raise broken DAG exception if trying to use pool that doesn't exist. Much like it does for accessing Variable that doesn't exist. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
