Steve Larkin created SPARK-25803:
------------------------------------
Summary: The -n option to docker-image-tool.sh causes other
options to be ignored
Key: SPARK-25803
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
(NB: I don't believe the above has a bearing; I imagine this issue is present
also on linux and can confirm if needed.)
Reporter: Steve Larkin
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.
