Congratulations on your first Pull Request and welcome to the Apache Airflow community! If you have any issues or are unsure about any anything please check our Contribution Guide (https://github.com/apache/airflow/blob/main/CONTRIBUTING.rst)
Here are some useful points:

Pay attention to the quality of your code (ruff, mypy and type annotations). Our pre-commits will help you with that.
In case of a new feature add useful documentation (in docstrings or in docs/ directory). Adding a new operator? Check this short guide Consider adding an example DAG that shows how users should use it.
Consider using Breeze environment for testing locally, it's a heavy docker but it ships with a working Airflow and a lot of integrations.
Be patient and persistent. It might take some time to get a review or get the final approval from Committers.
Please follow ASF Code of Conduct for all communication including (but not limited to) comments on Pull Requests, Mailing list and Slack.
Be sure to read the Airflow Coding style.
Apache Airflow is a community-driven project and together we are making it better 🚀.

I notice the type is added at the end of the docstring. I don't see this pattern in other databricks operators. Do we need to keep it as we have already annotated it in the __init__ method?

Other operators don't use data classes, that's why there are no types there.

Yep, but I thought type annotation was enough? not a blocker, though

nitpick: Should we change the type to dict instead?

stikkireddy · 2023-08-09T16:44:21Z

hey @potiuk is anything holding this up from being merged? Is it just the type hint comment?

potiuk · 2023-08-09T17:59:13Z

hey @potiuk is anything holding this up from being merged? Is it just the type hint comment?

Mostly just lack of ping after you fixed the tests to run the workflows I think. Generally if you see that you PR needs attention, just comment on it. Otherwise it might be very easily missed that you fixed tests. It's up to the author to bring attention of those who might review it - when you have 1 PR to care about - some reviewers have likely 40-50 to look at.

… type hints

stikkireddy · 2023-08-10T13:25:58Z

@potiuk i updated branch a little while please let me know if this works.

potiuk · 2023-08-13T21:55:51Z

@potiuk i updated branch a little while please let me know if this works.

Some other PR got merged in the meantime - you need to rebase and resolve conflict. Can you also respond please to all the comments in this PR and confirm that they've been addressed? There were lots of comments from @alexott and I am not sure if all have been addressed.

@potiuk based on @alexott's comment is this possible to push through? I also resolved all the issues and made the suggested changes.

Let's see If our CI agrees to merge it. I just approve it for runing - let me know if/when it succeds (or fails) @stikkireddy

stikkireddy · 2023-08-22T14:20:47Z

@potiuk seems like it failed due to static checks, i will take a look at the type hints. and ping you again once they are resolved.

airflow/providers/databricks/operators/databricks.py

+        if name is not None:
+            self.json["name"] = name
+        if tags is not None:
+            self.json["tags"] = tags


Since json is a templated field, attempting to modify it in this way will fail/not work as expected if the input arg is a string (e.g. "{{ var.json....}}" or an XComArg (meaning it's an output of a previous task). Template fields are not rendered until just before the execute method is called.

It would be best to move modifying json (and generally any template field) to the execute method instead.

That's behaviour isn't different from other databricks operators: https://github.com/apache/airflow/blob/main/airflow/providers/databricks/operators/databricks.py#L334

To illustrate the point, let's use this example DAG where we define the json arg in a previous task and use its output:

from __future__ import annotations from pendulum import datetime from typing import TYPE_CHECKING, Sequence from airflow.decorators import dag, task from airflow.models.baseoperator import BaseOperator if TYPE_CHECKING: from airflow.utils.context import Context class DatabricksCreateJobsOperator(BaseOperator): template_fields: Sequence[str] = ("json", "databricks_conn_id") def __init__( self, *, json: dict | None = None, name: str | None = None, tags: dict[str, str] | None = None, **kwargs ): super().__init__(**kwargs) self.json = json or {} if name is not None: self.json["name"] = name if tags is not None: self.json["tags"] = tags def execute(context: Context) -> None: pass @dag(start_date=datetime(2023, 1, 1), schedule=None) def derived_template_fields(): @task def push_json() -> dict[str, str]: return {"key1": "val1", "key2": "val2"} json = push_json() DatabricksCreateJobsOperator( task_id="create_job_w_json", json=json, name="some_name", tags={"key3": "value3"} ) derived_template_fields()

DAG parsing fails with:

Running: airflow dags reserialize [2023-08-31T14:29:57.796+0000] {utils.py:430} WARNING - No module named 'paramiko' [2023-08-31T14:29:57.816+0000] {utils.py:430} WARNING - No module named 'airflow.providers.dbt' [2023-08-31T14:29:58.533+0000] {dagbag.py:539} INFO - Filling up the DagBag from /usr/local/airflow/dags [2023-08-31T14:29:58.615+0000] {dagbag.py:347} ERROR - Failed to import: /usr/local/airflow/dags/derived_template_fields.py Traceback (most recent call last): File "/usr/local/lib/python3.11/site-packages/airflow/models/dagbag.py", line 343, in parse loader.exec_module(new_module) File "<frozen importlib._bootstrap_external>", line 940, in exec_module File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed File "/usr/local/airflow/dags/derived_template_fields.py", line 50, in <module> derived_template_fields() File "/usr/local/lib/python3.11/site-packages/airflow/models/dag.py", line 3798, in factory f(**f_kwargs) File "/usr/local/airflow/dags/derived_template_fields.py", line 41, in derived_template_fields DatabricksCreateJobsOperator( File "/usr/local/lib/python3.11/site-packages/airflow/models/baseoperator.py", line 436, in apply_defaults result = func(self, **kwargs, default_args=default_args) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/airflow/dags/derived_template_fields.py", line 27, in __init__ self.json["name"] = name ~~~~~~~~~^^^^^^^^ TypeError: 'PlainXComArg' object does not support item assignment

Even if we change the json arg assignment to use the classic XCom Jinja template approach (i.e. json = "{{ ti.xcom_pull(task_ids='push_json') }}"), the DAG fails to parse:

Perhaps it's possible users haven't needed a use case for predefining a json arg from a previous task, Airflow Variable, DAG Param, etc. (accessed by a Jinja templates).

Seems like there is now some movement on addressing #29069 to prevent this in the future too.

@josh-fell well spotted, that's a relevant concern! Since there is a separate ticket to address this issue, would it be okay if we consider this change outside of the scope of the current PR?

Totally fair. All of the Databricks operators would need to be cleaned up, but I also haven't heard of anyone running into this issue within their use cases.

I can log a separate issue and maybe we can get some folks to contribute! It's a solid "good first issue".

That's great, thanks a lot, @josh-fell! Please share the ticket once you create it - it's valuable and relevant.

Sorry for the mighty delay here, just got around to logging the issue.

Hey @stikkireddy, you've come a long way on this - is there any chance you could resolve the conflicts & have the CI tests pass, it feels like we're super close to merging this feature.

Is there a reason we need/want to pin it to <1.0.0?

Lee-W

Left a few questions but they're non-blockers. Also we might need to fix the CI failures.

Why limit to specific version? we rarely do this

I also don't understand if this is dependency or extra dependency ?

Should be rebased now. The issue should be fixed with 3 PRs I did during the last few days.
