> In ambari-web/app/utils/configs/config_property_helper.js, the value of masterComponentHostsInDB.findProperty('component', 'RESOURCEMANAGER').hostName is calculated irrespective if Yarn resourcemanager is configured or not. In cases, where Yarn resourcemanager is not configured, masterComponentHostsInDB.findProperty('component', 'RESOURCEMANAGER') will result in undefined and will eventually result in Uncaught TypeError while trying to get the value of hostName.
