Java 创建节点时，客户端获取org.elasticsearch.discovery.MasterNotDiscoveredException

我正在使用下面的代码创建elasticsearch的客户端节点。直到现在，我才突然发现了MasterNotDiscoveredException。我已将配置值更改为，但问题仍然是一样的

discovery.zen.ping.multicast.enabled:false

如果我切换到TransportClient，同样的情况也会发生。请让我知道节点客户端有什么问题

public static Client createESClient() {
    // creating a client node
    Node node =
        nodeBuilder().clusterName(CLUSTERNAME).client(true).data(false)
            .node();
    Client client = node.client();
    LOGGER.debug("the node has been created ");
    return client;
}

我也被困在这里，所以切换到使用“传输客户机”，它似乎工作完美。考虑添加标签，ActudiScript 2，java客户端。增加发现。
