org.apache.ambari.server.controller.spi.ResourceProvider.updateResources()
Update the resources selected by the given predicate with the properties from the given request object. @param request the request object which defines the set of propertiesfor the resources to be updated @param predicate the predicate object which can be used to filter whichresources are updated @return the request status @throws SystemException an internal system exception occurred @throws UnsupportedPropertyException the request contains unsupported property ids @throws NoSuchResourceException the resource instance to be updated doesn't exist @throws NoSuchParentResourceException a parent resource of the resource doesn't exist

    Request request = PropertyHelper.getUpdateRequest(properties, mapRequestProps);


    // update the cluster named Cluster102
    Predicate  predicate = new PredicateBuilder().property(
        ClusterResourceProvider.CLUSTER_NAME_PROPERTY_ID).equals("Cluster102").toPredicate();
    provider.updateResources(request, predicate);
