@Sergey Maybe they have added the feature in latest release! It wasn't there when this question was asked! CLI was used to kill apps back then. Thanks for pointing out the correction :) – France

You should add yarn.resourcemanager.webapp.ui-actions.enabled=true to your yarn-site.xml to enable this button (if its not visible).
