>                 URL: https://issues.apache.org/jira/browse/SPARK-25803
>             Project: Spark
>          Issue Type: Bug
>          Components: Kubernetes
>    Affects Versions: 2.4.0
>         Environment: * OS X 10.14
>  * iTerm2
>  * bash3
>  * Docker 2.0.0.0-beta1-mac75 (27117)
> (NB: I don't believe the above has a bearing; I imagine this issue is present 
> also on linux and can confirm if needed.)

> To reproduce:-
> 1. Build spark
>  $ ./build/mvn -Pkubernetes -DskipTests clean package
> 2. Create a Dockerfile (a simple one, just for demonstration)
>  $ cat > hello-world.dockerfile <<EOF
>  > FROM hello-world
>  > EOF
> 3. Build container images with our Dockerfile
>  $ ./bin/docker-image-tool.sh -R hello-world.dockerfile -r docker.io/myrepo 
> -t myversion build
> The result is that the -R option is honoured and the hello-world image is 
> built for spark-r, as expected.
> 4. Build container images with our Dockerfile and the -n option
>  $ ./bin/docker-image-tool.sh -n -R hello-world.dockerfile -r 
> docker.io/myrepo -t myversion build
> The result is that the -R option is ignored and the default container image 
> for R is built
> docker-image-tool.sh, uses 
> [getopts|http://pubs.opengroup.org/onlinepubs/9699919799/utilities/getopts.html]
>  in which a colon, ':', signifies that an option takes an argument.  Since -n 
> does not take an argument it should not have a colon.
