    ClassificationAssociateRequest classificationAssociateRequest = new ClassificationAssociateRequest();
    classificationAssociateRequest.setEntityGuids(Arrays.asList(entityGuid));

    AtlasClassification atlasClassification = new AtlasClassification();
    atlasClassification.setTypeName("sensitive_data");
    atlasClassification.setPropagate(false);
