我試圖用YCSB加載一些數據到彈性搜索使用YCSB，但我經常會得到一個錯誤NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{gdVShcjUToSDe3eJkHJNxw}{192.168.3.87}{192.168.3.87:9300}]]上彈性搜索
這裏是我的彈性搜索節點配置。
cluster.name: my-application
node.name: reconf-6
network.host: 192.168.3.87
http.port: 9200
transport.tcp.port: 9300
transport.host: 0.0.0.0
discovery.zen.ping.unicast.hosts: ["elasticsearch-1"]
path.data: data_mount/es
path.logs: data_mount/es
我首先啓動了10個這樣的節點，通過curl -XGET 'http://elasticsearch-1:9200/_cluster/state?pretty'我可以看到10個節點在集羣中。
然後我試着在遠程模式下運行YCSB。然後，它報道的例外：
Exception in thread "Thread-3" NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{gdVShcjUToSDe3eJkHJNxw}{192.168.3.87}{192.168.3.87:9300}]]

在YCSB代碼啓動客戶端的部分如下：
if (remoteMode) {
settings.put("client.transport.sniff", true)
.put("client.transport.ignore_cluster_name", false)
.put("client.transport.ping_timeout", "30s")
.put("client.transport.nodes_sampler_interval", "30s");
// Default it to localhost:9300
String[] nodeList = props.getProperty("es.hosts.list", DEFAULT_REMOTE_HOST).split(",");
System.out.println("Elasticsearch Remote Hosts = " + props.getProperty("es.hosts.list", DEFAULT_REMOTE_HOST));
TransportClient tClient = new PreBuiltTransportClient(settings.build());
for (String h : nodeList) {
String[] nodes = h.split(":");
try {
tClient.addTransportAddress(new InetSocketTransportAddress(
InetAddress.getByName(nodes[0]),
Integer.parseInt(nodes[1])
));
} catch (NumberFormatException e) {
throw new IllegalArgumentException("Unable to parse port number.", e);
} catch (UnknownHostException e) {
throw new IllegalArgumentException("Unable to Identify host.", e);
}
}
client = tClient;
}
