This can be seen with `BashOperator`’s `bash_command` argument. If you search [this documentation page](https://airflow.apache.org/docs/apache-airflow/stable/howto/operator/bash.html), the argument is used both to pass a command directly, and a path to a `.sh` file. The mechanism is done by checking `template_fields` and `template_ext`; if a field is listed in `template_fields`, *and the value ends with one of the value in `template_ext`, the value will be treated as a path and the target file read as a Jinja2 template to render the actual field value at runtime. The logic is implemented here: https://github.com/apache/airflow/blob/fc0250f1d5c43784f353dbdf4a34089aa96c28e5/airflow/models/baseoperator.py#L1047-L1054 `SparkKubernetesOperator` has https://github.com/apache/airflow/blob/fc0250f1d5c43784f353dbdf4a34089aa96c28e5/airflow/providers/cncf/kubernetes/operators/spark_kubernetes.py#L45-L47 So `application_file` will be templated if the file extension is `.json`, `.yaml`, or `.yml`. -- This is an automated message from the Apache Git Service.
