… maintainability The ResumableJobMixin implementation for SparkSubmitOperator previously had YARN, Kubernetes, and Standalone backend logics interleaved directly inside each mixin method. This scattered per-backend logic across multiple methods. Decoupling these by introducing specialized strategy classes per backend isolates the deployment-specific details, making the operator easier to maintain and extend.

Description
The
ResumableJobMixinimplementation forSparkSubmitOperatorpreviously had YARN, Kubernetes, and Standalone backend logics interleaved directly inside each mixin method. This scattered per-backend logic across multiple methods. Decoupling these by introducing specialized strategy classes per backend isolates the deployment-specific details, making the operator easier to maintain and extend.This refactor:
_SparkSubmitDeploymentBackend,_KubernetesSparkSubmitBackend,_YarnSparkSubmitBackend,_StandaloneSparkSubmitBackend) to cleanly isolate the status and execution tracking logic of each deployment mode._backendcached property onSparkSubmitOperator.submit_job,get_job_status,is_job_active,is_job_succeeded,poll_until_complete,on_kill) directly to the active backend strategy.This improves maintainability while keeping public namespaces completely clean.
fixes #68505
