Description

As per the discussion on PR 834 (NIFI-1831), the singleton pattern of NiFiProperties.getInstance() is being removed from the 1.0 release. It should be marked as deprecated in 0.x. A NiFiPropertiesLoader class will be provided and the contexts (processors, reporting tasks, controller services) will gain access to an instance of application properties.
