spark.kubernetes.executor.pvc.resizeIntervalto default to5minand to accept only0or a positive multiple of 5 minutes.Why are the changes needed?
Given that PVC expansion is a heavy operation (which typically takes over 1 minutes), restricting to 5-minute units (and defaulting to 5 minutes) gives a sensible out-of-the-box configuration once the plugin is registered, and prevents misconfigured intervals that would only add load on the K8s API server.
Does this PR introduce any user-facing change?
No (unreleased config).
How was this patch tested?
Pass the CIs with the newly added test case.
