[jira] [Created] (AIRFLOW-1786) Upstream Sensor skipped but whole
DAG fails
Felix Yuan created AIRFLOW-1786:
-----------------------------------
Summary: Upstream Sensor skipped but whole DAG fails
Key: AIRFLOW-1786
URL: https://issues.apache.org/jira/browse/AIRFLOW-1786
Project: Apache Airflow
Issue Type: Bug
Components: DAG
Affects Versions: Airflow 1.8
Reporter: Felix Yuan
Priority: Minor
I have created a daily DAG, which first monitor whether a file is ready on FTP server, then execute an ETL operation. If someday the file is missing, this is expected, so I set the "soft_fail" as True to simply skipped the FTP sensor.
During execution, I see the task of "FTP sensor" is surely be skipped, but the whole DAG is marked as failed.
My expectation is the upstream task (FTP Sensor) is skipped, then all downstream tasks are skipped as well.
