Github user jiangxb1987 commented on the issue: https://github.com/apache/spark/pull/20553 IIUC the `spark.kubernetes.executor.cores` here is just a special case for `spark.executor.cores`, for k8s backend, you shall still have to handle float values if you're to read the value of `spark.kubernetes.executor.cores`, for instance, in dynamic allocation. If that is the case here, I don't see much benefit of bringing in a new conf here.
