Konstantinos Karanasos commented on YARN-2883: ---------------------------------------------- Yep, I will address the visibility comment -- I just wanted to first do the refactoring fast, so that I get your feedback. Regarding the findbug, I tried to fix the problem by adding a @SuppressWarnings("unchecked"), but it does not seem to work.
