[jira] [Created] (SPARK-22994) Require a single container image for Spark-on-K8S

             Summary: Require a single container image for Spark-on-K8S
                 Key: SPARK-22994
                 URL: https://issues.apache.org/jira/browse/SPARK-22994
             Project: Spark
          Issue Type: Improvement
          Components: Kubernetes
    Affects Versions: 2.3.0
            Reporter: Marcelo Vanzin


Current k8s backend requires 3 separate container images to be provided by the user to submit an app. The 3 images are pretty much the same except for the entry point.

Instead, we should require a single image by default, but still allow the user to override individual images (e.g. executor) if desired.

This should also make it easier to publish an "official" Spark docker image, and should simplify things like the {{build-push-docker-images.sh}} script.
