From the description the CDH version used was 5.3.2, but currently the latest version was already 5.7 , are there any plan to upgrade the test environment? It would be a bad idea for the tester to do it by himself, as it will take his/her time that should be used for the actual test. i.e the new spark version was 1.6, many new features added,so have the newer stable version would be more useful.
