我从Elasticsearch收到以下错误。

我在Ubuntu上运行Elasticsearch 1.7.2。
我在elasticsearch.yml中所做的更改
################################### 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
连接代码
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;
}
从弹性客户端获取数据
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);
}
}
我做错了什么？
答案 0 :(得分：1)
您的客户端和服务位于不同的群集中。客户端位于assetservice，服务器位于cliffservice。此外，请确保客户端可以连接到10.100.10.231的端口9300。
答案 1 :(得分：0)
最后我发现了问题。我在我的Java应用程序中使用elasticsearch-1.7.1。在我的本地计算机上安装了Elasticsearch-1.7.1，但在服务器中，elasticsearch的版本是1.7.2。那就是问题所在。我将服务器的弹性搜索降级到1.7.1，现在它运行正常。
