Question

我有一个SolrCloud集群（6.6）设置与5个节点的外部Zookeeper Ensemble（3.4.8）。最近，运行1个Zookeeper且id = 1的一台机器（ip1：port1）关闭了。这就是我为取代zookeeper所做的工作：

在另一台具有相同ID（= 1）的计算机上启动zookeeper。
更改4 live zookeeper中的zoo.cfg以匹配新的zookeeper服务器并重新启动。
更新solr.in.sh中的ZK_HOST变量以匹配新的zookeeper服务器。
重启solr。

之后，我的solr集群似乎运行良好，但在solr.log中，看起来solr客户端和zookeeper服务器仍然尝试连接到旧的zookeeper：

Solr log

Zookeeper日志：

我已经在添加/删除zookeeper中进行了一些搜索，但没有找到它的文档。我的zookeeper版本（3.4.7）不支持动态重新配置（在zookeeper 3.5中）。有没有办法可以从ensemble手动删除/添加zookeeper服务器？

感谢您的关注！

将zookeeper服务器替换为zookeeper集合（使用SolrCloud）
