Robert Metzger commented on FLINK-28915:
----------------------------------------

Thanks a lot for the gist. This was the missing piece.
The difference between our approaches is the following: I'm loading S3 as a 
plugin.
This is my job defintion:
{code}
apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:
  name: basic-example
spec:
  image: flink:1.19.0-java11
  flinkVersion: v1_19
  mode: standalone
  flinkConfiguration:
    taskmanager.numberOfTaskSlots: "2"
    s3.endpoint: http://minio:9000
    s3.path.style.access: "true"
    s3.access.key: root
    s3.secret.key: password
  podTemplate:
    spec:
      containers:
        - name: flink-main-container
          env:
            - name: ENABLE_BUILT_IN_PLUGINS
              value: "flink-s3-fs-presto-1.19.0.jar"
  serviceAccount: flink
  jobManager:
    resource:
      memory: "2048m"
      cpu: 1
  taskManager:
    resource:
      memory: "2048m"
      cpu: 1
  job:
    jarURI: s3://dev/kafka-1.19.rocks.jar
    parallelism: 1
    upgradeMode: stateless
{code}

I'd suspect the plugins are not properly initialized when the code tries to 
load the jar.
