new 619ecf7dbda Fix: Add task context labels to driver and executor pods
for SparkKubernetesOperator reattach_on_restart functionality (#50803)
619ecf7dbda is described below

Fix: Add task context labels to driver and executor pods for
SparkKubernetesOperator reattach_on_restart functionality (#50803)
* Fix: Add task context labels to driver and executor pods for
SparkKubernetesOperator reattach_on_restart functionality (#41211)
* Fix formatting in test_spark_kubernetes.py
* Fix test assertions in SparkKubernetesOperator tests to handle task
context labels
* Fix whitespace issues in spark_kubernetes.py
* fix format and resolves failing tests
* Fix SparkKubernetesOperator test OOM issues
* Fix: Add task context labels to driver and executor pods for
SparkKubernetesOperator reattach_on_restart functionality (#41211)
* Fix whitespace issues in spark_kubernetes.py
* Clean up merge conflict markers in test_spark_kubernetes.py
* Fix test assertions for SparkKubernetesOperator task context labels
- Fixed test structure expectations in
test_adds_task_context_labels_to_driver_and_executor
- Changed assertion from created_body['spark']['spec'] to
created_body['spec']
- This matches the actual structure passed to
create_namespaced_custom_object after SparkJobSpec processing
* Fix compatibility issue with parent_dag attribute access
- Changed from checking is_subdag to parent_dag to match
KubernetesPodOperator implementation
- This ensures compatibility with older Airflow versions where is_subdag
may not exist
- Follows the same pattern used in the parent class for SubDAG handling
* Align _get_ti_pod_labels implementation with KubernetesPodOperator
- Use ti.map_index directly instead of getattr for consistency
- Convert try_number to string to match parent class behavior
- Convert map_index to string for label value consistency
- This ensures full compatibility with the parent class implementation
* feat: Add reattach functionality to SparkKubernetesOperator
Add reattach_on_restart parameter (default: True) to automatically reattach
to
existing Spark applications on task restart, preventing duplicate job
creation.
- Implement find_spark_job method for existing job detection
- Add task context labels for pod identification
- Maintain 100% backward compatibility
- Add comprehensive test coverage (2 new tests)
Fixes #41211

- Add task context labels to driver and executor pods when
reattach_on_restart=True
- Fix execution flow to maintain test compatibility
- Preserve deferrable execution functionality
- Add comprehensive reattach logic with proper pod finding
Fixes #41211
* Fix code formatting for static checks
- Remove extra blank line in SparkKubernetesOperator
- Add required blank line in test file
- Ensure compliance with ruff formatting standards
* update tests
