我在Ubuntu上運行Elasticsearch 1.7.2。

的變化，我在elasticsearch.yml取得

################################### Cluster ################################### 

# Cluster name identifies your cluster for auto-discovery. If you're running 
# multiple clusters on the same network, make sure you're using unique names. 
# 
cluster.name: cliffservice 




# Set the address other nodes will use to communicate with this node. If not 
# set, it is automatically derived. It must point to an actual IP address. 
# 
#network.publish_host: 192.168.0.1 
network.publish_host: 10.100.10.231 
# Set both 'bind_host' and 'publish_host': 
# 
#network.host: 192.168.0.1

連接代碼

public TransportClient getClient() { 
    Settings settings = ImmutableSettings.settingsBuilder().put("cluster.name", "cliffservice").build(); 
    TransportClient client = new TransportClient(settings); 
    client = client.addTransportAddress(new InetSocketTransportAddress(this.host, this.port)); 

    this.esclient = client; 

    return client; 
}

得到彈性客戶數據

SearchResponse response = Connection.getEsclient().prepareSearch("testindex").setTypes("testtype").execute() 
       .actionGet(); 

     if (response.getHits().getHits().length > 0) { 
      for (SearchHit hit : response.getHits().getHits()) { 
       CliffDomain cliffDomain = new CliffDomain(); 

       assetDomain.setCliffDomainId(hit.getId()); 
       assetDomain.setCliffDomainName((String) hit.sourceAsMap().get("clifftDomainName")); 

       searchResponse.add(cliffDomain); 

      } 
     }

我做錯了什麼？

最後我想出了問題。我在我的Java應用程序中使用了elasticsearch-1.7.1。在我的本地計算機Elasticsearch-1.7.1被安裝，但在服務器中elasticsearch的版本是1.7.2。這是問題所在。我將服務器的elasticsearch降級到1.7.1，現在工作正常。

這應該不是一個問題。傳輸客戶端應該與主版本中的任何服務器兼容。換句話說，任何1.X.Y客戶端都應該能夠連接到任何1.A.B服務器。我只是用1.7.1和1.7.2進行了測試，一切正常。所以，我懷疑這是某種配置問題。 – imotov

但是相信我這是我改變的唯一的東西。我沒有改變我的代碼中的任何東西，只是停止elasticsearch 1.7.2並開始1.7.1'cluster.name'作爲'cliffservice'並開始工作。 – user3306669

你能重現嗎？ – imotov

您的客戶和服務處於不同的羣集中。客戶端位於assetservice，服務器位於cliffservice。另外，請確保客戶端可以連接到10.100.10.231的端口9300。

我將代碼'assetservice'更改爲'cliffservice'仍然有相同的錯誤。這在我的本地計算機上運行良好，但是當我將它上傳到ubuntu服務器時，出現相同的錯誤。 9200＆9300端口在服務器上打開。 – user3306669

你可以在客戶機上運行'curl 10.100.10.231：9200'嗎？你有沒有嘗試打印出來，並仔細檢查客戶端上的連接主機和端口？ – imotov

我試圖 '遠程登錄本地主機9200'使用膩子回覆是 '根@懸崖DEV1：〜＃遠程登錄本地主機9200' '嘗試127.0.0.1 ...'' 連接到localhost.' '逃生字符是'^]'。' – user3306669
