Review comment:
Hey @abstractdog, thanks for the review.
Take a look at my notes here:
https://issues.apache.org/jira/browse/HIVE-24484?focusedCommentId=17369708&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17369708
tldr; These unit tests are launching two HMS within the same JVM (same
class-loader) and therefore they are able to modify each other's state where it
stored in static variables. This testing cannot be done any more.
