---------------------------------------
[~sjlee0] Thank you for looking at the patches. I didn't not get the error on
jetty-util locally ... I will keep modifying until both local and Jenkins pass.
> many undeclared used dependencies (and declared unused dependencies)

> Key: HADOOP-12048
> URL: https://issues.apache.org/jira/browse/HADOOP-12048
> Project: Hadoop Common
> Issue Type: Bug
> Components: build
> Affects Versions: 3.0.0
> Reporter: Sangjin Lee
> Assignee: Gabor Liptak
> Attachments: HADOOP-12048.1.patch, HADOOP-12048.2.patch,
> HADOOP-12048.3.patch, dependency-analysis.txt, hadoop-unused.txt
>
>
> Currently there are numerous undeclared used dependencies and declared unused
> dependencies in the hadoop projects.
> Undeclared used dependencies are easier errors to correct, and correcting
> them will lead to a better management of dependencies (enabling stricter
> dependency frameworks down the road).
> Declared unused dependencies are harder to resolve, as many may be legitimate
> runtime dependencies. But fixing them would lead to smaller profiles for
> hadoop projects.
> We can do a one-time scan of dependency issues and fix them. However, in the
> long run, it would be nice to be able to enforce those rules via maven
> plug-in.
