SergioShz opened a new issue #11234: URL: https://github.com/apache/airflow/issues/11234
**Apache Airflow version**: `apache-airflow (1.10.10)` **Environment**: `Docker version 19.03.12` - **OS** (e.g. from /etc/os-release): ``` NAME="Ubuntu" VERSION="18.04.5 LTS (Bionic Beaver)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Ubuntu 18.04.5 LTS" VERSION_ID="18.04" HOME_URL="https://www.ubuntu.com/"; SUPPORT_URL="https://help.ubuntu.com/"; BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"; PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"; VERSION_CODENAME=bionic UBUNTU_CODENAME=bionic ``` - **Kernel** (e.g. `uname -a`): `4.19.76-linuxkit` **What happened**: I'm testing this small DAG (see below) consisting of a simple task using PythonOperator. I'd like to exit the call with a exit code 0 when everything went fine, however airflow seems to be marking the task as failed when this happen. The log file: `[2020-10-02 09:44:13,081] {taskinstance.py:669} INFO - Dependencies all met for <TaskInstance: TEST_0.test_task 2020-10-02T09:43:00+00:00 [queued]> [2020-10-02 09:44:13,735] {taskinstance.py:669} INFO - Dependencies all met for <TaskInstance: TEST_0.test_task 2020-10-02T09:43:00+00:00 [queued]> [2020-10-02 09:44:13,736] {taskinstance.py:879} INFO - -------------------------------------------------------------------------------- [2020-10-02 09:44:13,737] {taskinstance.py:880} INFO - Starting attempt 1 of 1 [2020-10-02 09:44:13,737] {taskinstance.py:881} INFO - -------------------------------------------------------------------------------- [2020-10-02 09:44:14,288] {taskinstance.py:900} INFO - Executing <Task(PythonOperator): test_task> on 2020-10-02T09:43:00+00:00 [2020-10-02 09:44:14,291] {standard_task_runner.py:53} INFO - Started process 10800 to run task [2020-10-02 09:44:16,389] {logging_mixin.py:112} INFO - Running %s on host %s <TaskInstance: TEST_0.test_task 2020-10-02T09:43:00+00:00 [running]> 3a160363119b [2020-10-02 09:44:17,433] {logging_mixin.py:112} INFO - doing stuff inside task [2020-10-02 09:44:22,195] {logging_mixin.py:112} INFO - [2020-10-02 09:44:22,195] {local_task_job.py:103} INFO - Task exited with return code 0 ' **What you expected to happen**: I'm expecting the task marked as succed, or at least understand why airflow marks this task as failed despite of the exit code 0. **How to reproduce it**: Here is the code `import os from airflow import DAG from airflow.operators.python_operator import PythonOperator from airflow.utils.dates import days_ago default_args = { 'depends_on_past': False, 'start_date': days_ago(1), 'retries': 0, } DAG_NAME = 'TEST_0' SCH_INTERVAL = '0/1 * * * *' def task(): print('doing stuff inside task') sys.exit(0) with DAG( DAG_NAME, default_args=default_args, schedule_interval=SCH_INTERVAL, ) as dag: task_instance = PythonOperator( task_id='test_task', python_callable=task) ` And the status in the UI:  thanks! ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
