the class LabelsEndpointMerger method merge.

    final Set<LabelEntity> labelEntities = responseEntity.getLabels();
    final Map<String, Map<NodeIdentifier, LabelEntity>> entityMap = new HashMap<>();
    for (final NodeResponse nodeResponse : successfulResponses) {

    }
    LabelsEntityMerger.mergeLabels(labelEntities, entityMap);
    // create a new client response
