Review Comment:
To clarify, this was never an upgrade — 1.3.1 is unchanged. The PR had
relocated exec-maven-plugin's version management from hadoop-project up to the
root pom: hadoop-coverage's module-list guard runs via exec-maven-plugin, and
since that module inherits from hadoop-main (not hadoop-project) it couldn't
see hadoop-project's management, so it needed the version at the root — which
made the hadoop-project entry redundant, hence removed.
Since then I've reworked it so no shared poms are touched at all: root
pom.xml and hadoop-project/pom.xml are back to trunk, and the version is now
pinned locally in hadoop-coverage/pom.xml itself. So there's no longer any
shared or unrelated change, and nothing that needs a separate PR.

> 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 outdated.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.
