Fokko commented on issue #4283: [AIRFLOW-3450] Remove unnecessary sigint handler URL: https://github.com/apache/incubator-airflow/pull/4283#issuecomment-444676536 I'm running Docker (Cloud composer), but I don't get any explicit reason: ``` [2018-12-05 20:20:57,138] {jobs.py:401} ERROR - Got an exception! Propagating... Traceback (most recent call last): File "/usr/local/lib/airflow/airflow/jobs.py", line 376, in helper settings.configure_orm() File "/usr/local/lib/airflow/airflow/settings.py", line 180, in configure_orm engine = create_engine(SQL_ALCHEMY_CONN, **engine_args) File "/usr/local/lib/python3.6/site-packages/sqlalchemy/engine/__init__.py", line 391, in create_engine return strategy.create(*args, **kwargs) File "/usr/local/lib/python3.6/site-packages/sqlalchemy/engine/strategies.py", line 162, in create engine = engineclass(pool, dialect, u, **engine_args) File "/usr/local/lib/python3.6/site-packages/sqlalchemy/engine/base.py", line 1772, in __init__ self.echo = echo File "/usr/local/lib/python3.6/site-packages/sqlalchemy/log.py", line 217, in __set__ instance_logger(instance, echoflag=value) File "/usr/local/lib/python3.6/site-packages/sqlalchemy/log.py", line 173, in instance_logger def instance_logger(instance, echoflag=None): File "/usr/local/lib/airflow/airflow/bin/cli.py", line 85, in sigint_handler sys.exit(0) ``` So my initial thought was to just let the exception propagate.
