我正在使用Hortonworks Distribution，并使用ambari服务器安装了solr Solr版本5.5.2
我使用创建了收藏
/opt/lucidworks-hdpsearch/solr/bin/solr create_collection -p 8983 -d data_driven_schema_configs -c eim_log -s 2 -rf 1
我使用下面的Java代码创建客户端并添加文档：
SolrClient solr = new CloudSolrClient("server1:2181,serve2:2181,server3:2181/solr");
SolrInputDocument doc = new SolrInputDocument();
doc.setField(field.message, event.getMessage());
doc.setField(field.stacktrace, formatBody(event));
doc.setField(field.applicationName, getApplicationName());
doc.setField(field.applicationId, getApplicationId());
UpdateResponse ur = solr.add(collectionName,doc,5000);
但是在将文档添加到集合时，它失败并显示以下错误：

当我如下更改solr客户端时，相同的代码正在工作：
SolrClient solr = new HttpSolrClient(host)
非常感谢您的帮助。
