Question

我尝试使用API在Apache solr 4上创建新的集合，示例API为：

http://example.com:8983/solr/admin/collections?action=CREATE&name=col1&numShards=2&replicationFactor=1

我收到以下错误：

org.apache.solr.servlet.SolrDispatchFilter; [admin] webapp=null path=/admin/collections params={numShards=2&name=bisnis&replicationFactor=1&action=CREATE} status=500 QTime=2

我猜你没有为你的“SolrCloud”隐式或明确地运行zookeeper实例。

在启动Solr节点时，要启动zookeeper实例，请隐式添加-DzkRun。或者显式地-DzkHost = localhost：2181（显然你应该在你当地的端口2181上有一个正在运行的zookeeper实例）

然后运行您的查询。它将创建新的集合。
