             Summary: ResourceUtils.getResourceTypes() reloads the resource 
configuration every time
                 Key: YARN-6782
                 URL: https://issues.apache.org/jira/browse/YARN-6782
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: resourcemanager
    Affects Versions: YARN-3926
            Reporter: Daniel Templeton
            Priority: Minor


Many objects need to collect the list of configured resources upon creation.  
The only way do that now is by calling {{getResourceTypes()}}, which reloads 
the config.  The net result is that the config is loaded and reloaded over and 
over again during startup.
