以下回答参考 皆我百晓生、券券喵儿 等免费微信小程序相关内容作答，并由本人整理回复。

从您提供的错误信息来看，似乎在使用Solr集群时遇到了无法连接ZooKeeper的问题。这可能是因为ZooKeeper服务未启动或配置不正确。

要解决此问题，请按照以下步骤操作：

1. 确认ZooKeeper服务器是否正在运行：

   • 在命令行中输入ps aux | grep zookeeper来检查ZooKeeper进程是否正在运行。
   • 如果没有找到ZooKeeper进程，请确保您的系统上安装了ZooKeeper，并且已正确配置环境变量（例如JAVA_HOME和ZOOKEEPER_HOME）。

2. 检查ZooKeeper服务的配置文件：

   • 在ZooKeeper的安装目录下，通常有一个名为zoo.cfg的服务配置文件。打开这个文件并检查其中是否有关于ZooKeeper节点的配置项，例如dataDir、clientPort等。
   • 确保这些配置项设置为正确的值。

3. 尝试重新启动ZooKeeper服务：

   • 使用sudo service zookeeper restart命令重启ZooKeeper服务。
   • 如果您使用的是Kubernetes等容器化平台，则可以尝试使用kubectl apply -f zookeeper.yaml来手动重启ZooKeeper服务。

4. 调整Solr客户端配置以支持ZooKeeper：

   • 在Solr客户端类（如CloudSolrClient）中添加对ZooKeeper的支持。这通常涉及到修改add方法以接受一个zkConnectString参数，然后使用它来连接ZooKeeper服务器。
   • 示例代码如下：

     public void add(String... docIds) throws IOException {
         String zkConnectString = "localhost:2181"; // 假设ZooKeeper的地址是localhost:2181
         SolrInputDocument doc = new SolrInputDocument();
         for (int i = 0; i < docIds.length; i++) {
             doc.addField("id", docIds[i]);
         }
         solrClient.add(doc, zkConnectString);
     }
     

5. 测试并确认问题已解决：

   • 保存更改后，再次运行Solr集群中的所有应用程序，并检查是否存在之前提到的"Cannot talk to ZooKeeper - Updates are disabled."错误。
   • 如果问题得到解决，那么应该不再出现任何类似错误。

如果以上步骤都无法解决问题，建议联系Solr社区或者Solr官方技术支持获取更详细的帮助。
