> When I scan through the pom.xml of sub projects, I found this warning as
> below and attached screenshot
> {code}
> Definition of groupId is redundant, because it's inherited from the parent
> {code}
> I've tried to remove some of the lines with groupId definition, and the build
> on my local machine is still ok.
> {code}
> <groupId>org.apache.spark</groupId>
> {code}
> As I just find now <maven.version>3.3.9</maven.version> is being used in
> Spark 2.x, and Maven-3 supports versionless parent elements: Maven 3 will
> remove the need to specify the parent version in sub modules. THIS is great
> (in Maven 3.1).
