[西门呀在吹雪]

遇到同样的问题，你解决了吗？

[S_H-A_N]

端口用9300

[SSHorSSM]

集群名称默认为elasticsearch，没有修改过无需setting可以建立连接： Client client = new TransportClient().addTransportAddress(new InetSocketTransportAddress("", 9300)); 如果修改过集群的名称： Settings settings = ImmutableSettings.settingsBuilder() .put("cluster.name", "elasticsearch_01").build(); Client client = new TransportClient(settings) .addTransportAddress(new InetSocketTransportAddress("", 9300));

楼主解决了嘛

[美丽De大海]

2楼说的对 端口用9300 搭建集群的时候三台服务器也都是9300

netty包冲突了

[程语人生]

楼上一语道破天机，确实是netty冲突了，我解决如下，修改pom (不知道会不会带来其它问题)
