What about issues/restrictions around > Hadoop integration? On the hadoop integration side we would need help from someone running hadoop. We should at least verify that Druid running Java 11 can successfully submit tasks to a hadoop cluster and make sure there aren't any odd classpath issues. Hadoop itself doesn't support Java 11 yet, so the jobs themselves would still run with Java 8.
