@tariq-hasan - curious if you still plan to implement this for Spark Operator? We are looking into using Kueue for Spark Applications and this feature is a prerequisite.

@tariq-hasan I also need to integrate SparkApplication into Kueue. As @munali wrote, suspend/resume feature would enable seamless integration with Kueue.

Would you mind me taking over this issue from you? Actually my PR(#2387) has been already pushed. I'm really appreciated if you gave a review to my PR, too.

Moreover, I'm working on Kueue integraiton on my personal branch: https://github.com/everpeace/kueue/tree/kubeflow-spark-operator
