elasticsearch - NoNodeAvailableException [没有已配置的节点可用:

Question

如果我没有设置大小，我将获得10次点击:

SearchResponse sr = client.prepareSearch("xxx").setTypes("xxx")
                .setQuery(rangeQueryBuilder)
                .setQuery(queryBuilder)

但是当我设置尺寸大于12时:

SearchResponse sr = client.prepareSearch("xxx").setTypes("xxx")
                .setSize(13)
                .setQuery(rangeQueryBuilder)
                .setQuery(queryBuilder)

我得到这个问题:
NoNodeAvailableException [已配置的节点均不可用:[{gw_172.28.236.85:40001} {oHcfPhqFQDSW4opwUuzCpA} {P1GbtDqrRda4nlbRRBmW1Q} {172.28.236.85} {172.28.236.85:40101ed} {xpack
我的Java连接代码:

    public static TransportClient client() throws UnknownHostException {
    if (client != null) {
        return client;
    }
    synchronized (esConnection_old.class) {
        if (client == null) {
            Settings settings = Settings.builder().put("cluster.name", ClusterName)
                    .put("client.transport.sniff", false)
                    .put(SecurityKey, basicAuthHeaderValue(SecurityUser, SecurityPassword))
                    .build();

            client = new PreBuiltTransportClient(settings);


            String[] oneInstance = GatewayIpPorts.split(",");
            for (String item : oneInstance) {
                String[] ipPort = item.split(":");
                client.addTransportAddresses(new TransportAddress(InetAddress.getByName(ipPort[0]), Integer.parseInt(ipPort[1])));
            }
            return client;
        }
        return client;
    }
}

通常，当Elasticsearch需要在节点上执行某些操作(分片，索引和搜索数据的分配)并且找不到可满足这些请求的节点时，就会出现此异常。
您可以看一下NoNodeAvailableException代码并追溯到它，我看这是最新的代码，找不到要尝试执行的搜索操作的None of the configured nodes were available:。
请提供您的elasticsearch版本，并确认是否因为大小参数值大于10而导致此异常？
