Duo Xu commented on HADOOP-15190:
---------------------------------
[~aw] Very cool job.
My initial thought is also to use openclover. But I am thinking jacoco may be
more widely used in java world.
Here is the command to run with jacoco
{code:java}
mvn test -Dmaven.test.failure.ignore=true -Dhadoop.skip-jacoco=false //
run tests with jacoco enabled
mvn jacoco:report-aggregate -Dhadoop.skip-jacoco=false // generate
aggregate report under hadoop-coverage//target/site/jacoco-aggregate{code}
The report screenshot is attached.
> Use Jacoco to generate Unit Test coverage reports

> 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 outdated.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.
