Hi all, I'm trying to run basic-checkpoint-ha.yaml with flink-kubernetes-operator. I installed minikube with all default settings, and deployed the operator according to quick start guide. However, I'm keep getting the following error:

ERROR org.apache.flink.runtime.entrypoint.ClusterEntrypoint [] - Fatal error occurred in the cluster entrypoint.

From previous discussions I learned this might be related to permission issues, so I tried the following fix:

securityContext:
        runAsUser: 9999
        runAsGroup: 9999
        fsGroup: 9999

under

podTemplate

. But it's still not working and getting the same error. I'm wondering if I'm missing any configurations, or if anything not default should be applied to minikube. Any help is appreciated and thanks in advance. I'm using minikube v1.25.2 and Flink v1.16.1, if it matters.
