The script is running via DAG. bash # # Licensed to the Apache Software Foundation However, if a sub-command exits with non-zero value Airflow will not recognize it as failure unless the whole shell exits with a failure. Exit code 99 (or another set in skip_exit_code) will throw an airflow. Airflow performs a few more operations after the execution of the operator's execute method and of this code is not executed the task will always be marked as failed. In addition, if you dig further into the code and look at the SubprocessHook that is called as part of BashOperator. 4. The spark job takes some parameters. How to exit DAG as normal without other tasks execution in AirFlow. 0, pods were able to run the tasks and after successful completion, it is restarting with CrashLoopBackoff status. Exit code ``99`` I have a simple Airflow DAG which has only one task - stream_from_twitter_to_kafka Here is the code for the DAG: default_args = { "owner": "me Airflow task running tweepy exits with return code -6.

On Linux, the mounted volumes in container use the native Linux filesystem user/group permissions, so you have to make sure the container and host computer have matching file permissions.
