elchao96 opened a new issue, #29903:
URL: https://github.com/apache/airflow/issues/29903
### Apache Airflow version
Other Airflow 2 version (please specify below)
### What happened
When running a DAG that is structured like:
```
@dag{dag_id="my_dag", default_args={"retries":0"}}
def dag():
op = MyOperator.partial(task_id="my_task", retries=3).expand(...)
```
The following test fails:
```
def test_retries(self) -> None:
dag_bag = DagBag(dag_folder=DAG_FOLDER, include_examples=False)
dag = dag_bag.dags["my_dag"]
for task in dag.tasks:
if "my_task" in task.task_id:
self.assertEqual(3, task.retries) # fails - this is 0
```
When printing out `task.partial_kwargs`, and looking at how the default args
and partial args are merged, it seems like the default args are always taking
precedence, even though in the `partial` global function, the `retries` do get
set later on with the task-level parameter value. This doesn't seem to be
respected though.
### What you think should happen instead

### How to reproduce
If you run my above unit test for a test DAG, on version 2.4.3, it should
show up as a test failure.
