>             Project: Spark
>          Issue Type: Improvement
>          Components: Kubernetes
>    Affects Versions: 2.3.0, 2.3.1, 2.3.2, 2.4.0
>            Reporter: Rob Vesse
>            Priority: Major

> The current Dockerfiles provided by the project for running on Kubernetes do not include a [USER directive|https://docs.docker.com/engine/reference/builder/#user] which means that they default to running as {{root}}.  This may lead to unsuspecting users running their Spark jobs with unexpected levels of privilege.
> The project should follow Docker/K8S best practises by including {{USER}} directives in the Dockerfiles.
