SolrCloud - 如何解决 "Could not find collection configName"

Question

我正在尝试以 SolrCloud 模式启动 Solr。我从 collection1 创建了一个新集合，并通过设置属性 name=logmail 在文件 core.properties 中更改了其名称。

但是当我启动 Solr 时，出现以下错误

$ java -Dcollection.configName=logmail -DzkRun -Dnumshards=2 -DBootstrap_confdir=./solr/logmail/conf -jar start.jar

看起来 Solr 在文件系统上根据您的命令进行集合的内容与 Zookeeper 中的内容之间可能存在差异。

这些很难修复；如果可能的话，我建议从zookeeper中删除您的配置文件并重新加载它们。
