我已经下载了Solr 4.10.3，使用提供的安装程序运行服务器，并且可以使用SolrJ（v。4.0.0）通过使用HttpSolrServer插入文档而没有任何问题。但是当我尝试使用CloudSolrServer时，我无法插入任何文档。我读过的官方文档，并尝试以下操作：当我使用SolrJ和SolrCloud时，为什么我会得到“KeeperErrorCode = NoNode for /clusterstate.json”？
SolrServer solr;
String zkHostString = "localhost:9983/solr";
solr = new CloudSolrServer(zkHostString);
但我得到的org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /clusterstate.json例外，当我尝试solr.add(document);：
