> Currently Hadoop is using maven-clover2-plugin for code coverage, which is
> outdated. And Atlassian open-sourced clover last year so license cannot be
> purchased although we can switch to use the license-free version called
> "openclover".
> This Jira is to replace clover with Jacoco, which is actively maintained by
> the community.
