Question

我是MacOS上Solr 7.3.0的新手。

我正在尝试构建Solr云服务器。

object CloudSolRServerBuilder {
  def build(zkHost: String): CloudSolrClient = {
    new CloudSolrClient.Builder(mutable.Buffer(zkHost)).build()
  }

我收到以下错误信息

我查看了localhost：8983，我可以访问Solr Admin UI。

如果查看docs，您会看到传递给CloudSolrClient的字符串不正确，它应该是这样的：

String zkHostString = "zkServerA:2181";

（实际上，如果你有一个zk合奏，就像这样的字符串一样的列表）。

无法初始化HttpClusterStateProvider（是/是Solr服务器，[localhost：8983]，向下？）
