我的弹性搜索集群（版本2.0）已启动且节点客户端已成功构建，但由于某些原因，我在使用节点客户端运行查询时收到以下错误。

我甚至禁用了＃34;多播＆＃34;按照这个post - 仍然没有运气。令人惊讶的是，我可以从感觉上访问elasticsearch。关于出了什么问题的任何线索？

2 个答案:

答案 0 :(得分：3)

我遇到了相同的错误消息，并且无法先了解问题。我正在笔记本电脑上使用远程服务器上的Elasticsearch数据节点开发节点客户端Java应用程序。对于生产用途，我需要在此远程服务器上部署Java应用程序。

我将Java应用程序配置为仅与本地主机通信（现在位于同一主机上）：

elasticsearch.discovery.zen.ping.unicast.hosts=127.0.0.1

得到了同样的例外

ClusterBlockException[blocked by: [SERVICE_UNAVAILABLE/1/state not recovered / initialized];]

查看日志我也发现了这个条目：

[WARN] [TP-Processor2] DiscoveryService.waitForInitialState -> [cerbera] waited for 30s and no initial state was set by the discovery

基本上，问题是：为什么不找到Elasticsearch数据节点？我更改了端口范围并使用了multicast设置 - 但没有成功。

最后，我检查了elasticsearch.yml，发现数据节点没有收听localhost（127.0.0.1），而是收听了以太网接口192.168.1.2。

network.host: 192.168.1.2
http.port: 9200

最后的改变很简单，我只需要重新配置节点客户端配置以与正确的接口进行通信

elasticsearch.discovery.zen.ping.unicast.hosts=192.168.1.2

现在我的节点客户端正在通过正确的界面与elasticsearch 交谈。完成工作。

答案 1 :(得分：0)

我遇到了同样的问题（使用 k8s ）我终于更换了我的弹性图像，问题解决了... 从 6.5.4-debian-9-r41 移至 6.8.16-debian-10-r5 (using bitnami images) 我知道这不是最好的答案 - 但我真的尝试了建议的答案，但没有任何效果对我有用。所以我的建议是更新到更新更好的版本。 （docker 让这一切变得简单:) ）
