我们尝试使用MapReduce批量索引将数据导入SolrCloud。我们在缩减阶段遇到问题，无法找到solr.xml。我们创建了一个'twitter'集合，但查看日志，在solr.xml无法加载后，它使用默认值并尝试创建'collection1'（失败）和'core1'（成功）SolrCore。我不确定我们是否需要创建自己的solr.xml以及放置它的位置（我们尝试将它放在几个地方，但似乎没有加载）。以下是日志：

solr查找solr.home参数并在那里搜索 solrConfig.xml 文件。如果没有则尝试加载默认配置。
看起来你的索尔之家是

检查solrconfig.xml文件的文件夹 如果没有，请从solr的示例目录中复制一个 如果有，则将文件/文件夹权限与服务器实例匹配
