test case
public class TestMetaClient extends TestCase {
private static final Logger LOGGER = LoggerFactory.getLogger(TestMetaClient.class);
private final String address = "10.27.20.112";
private final int port = 9559;
private MetaClient metaClient;
public void testListHosts() {
if (metaClient == null) {
metaClient = new MetaClient(address, port);
}
metaClient.listHosts();
}
}
运行testListHosts()方法报错：
