Question

我在我的测试环境中设置了CDCR，它完美运行直到我上传 security.json文件到目标和源的Zookeeper集群 SolrClouds。 security.json文件对于云以及云都是相同的集合名称。 Source有下一个错误：

Request to collection col01 failed due to (401)

知道我应该怎么解决它？谢谢！

我遇到了同样的问题，似乎目标SolrCloud正在尝试使用PKIAuthenticationPlugin验证来自源的传入请求，但由于默认情况下两个源节点都没有在目标上注册，后者给出了以下错误：

错误（qtp1265210847-32）[] o.a.s.s.PKIAuthenticationPlugin解密失败，密钥必须错误

在对PKIAuthenticationPlugin.java进行一些调查后，我发现以下一段代码会拒绝身份验证请求：

Public Key getRemotePublicKey(String nodename) {
  if(!cores.getZkController().getZkStateReader().getClusterState(). getLiveNodes().contains(nodename)) 
return null;
}

因此，为了解决这个问题，我只是将源的节点名称（位于/live_nodes部分）添加到目标Zookeeper中，并且复制开始使用security.json双方强制执行。< / p>

如果启用了身份验证，则Solr CDCR不起作用
