Examples of org.apache.ambari.server.state.DesiredConfig$HostOverride

org.apache.ambari.server.state.DesiredConfig
Used to represent an override on a host.

    Map<String, DesiredConfig> map = new HashMap<String, DesiredConfig>();


    for (HostConfigMapping e : hostConfigMappingDAO.findSelected(
        clusterId, hostEntity.getHostName())) {

      dc.setUser(e.getUser());
      map.put(e.getType(), dc);
      
    }
