dongjoon-hyun opened a new pull request, #39070: URL: https://github.com/apache/spark/pull/39070
### What changes were proposed in this pull request? This PR improve `ExecutorPodsAllocator.onNewSnapshots` by removing duplications at `k8sKnownExecIds` and `k8sKnownPVCNames`. ### Why are the changes needed? The existing variables have lots of duplications because `snapshots` is `Seq[ExecutorPodsSnapshot]`. ``` val k8sKnownExecIds = snapshots.flatMap(_.executorPods.keys) ``` For example, if we print out the values, it looks like the following. ``` 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 3 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 3 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 3 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 3 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 1 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 2 22/12/15 07:09:37 INFO ExecutorPodsAllocator: 3 ``` ### Does this PR introduce _any_ user-facing change?
