Hi @dombizita thank you for your work on this one. I have merged back the master into HDDS-5447-httpfs branch, and also merged the changes to your PR's branch, in order to have the CI changes and reduce our testing footprint on the branches and PRs whenever it is possible.
Please don't forget to update your local branches.

It seems that some of the jars are not removed from jar-report.txt, although they were added in #2536, @dombizita would you mind take a look and check if there is anything else on the list that we can remove after the tests were removed besides removing the unnecessary ones marked by the dependency check? If there is anything that remains, we have to change the LICENSE.txt in hadoop-ozone/dist/src/main/license/bin as well at the end of the day.

Thanks for addressing this one, lgtm, +1.

Note: junit.jar, and json-simple.jar is still on the list in the branch, and not on master.
I am creating a JIRA to track those as well, and as we have json-smart, and we don't need junit we should remove those from the dist dependencies.

Created https://issues.apache.org/jira/browse/HDDS-5722 to track the two remaining questionable jars.
