Issue 1:
I'm encountering the same bug reported in https://issues.apache.org/jira/browse/AIRFLOW-3534, with airflow 1.10.12.

The bug goes away by setting get_logs=False in the KubernetesPodOperator. Reproduced with multiple dags and tasks.

Issue 2:
Apache Airflow version

2.2.3 (latest released)

What happened

In the configuration file, we specified a sql_alchemy_conn_cmd so that the main sql alchemy connection is loaded from a command. However, when using such a configuration and running any dag / task, we get the following error:

What you expected to happen

Tasks should run without error when using sql_alchemy_conn_cmd

How to reproduce

Use a sql_alchemy_conn_cmd file, and any task that you run will try to use sqlite instead of the configured database connection and cause all sorts of havoc.
