我已经配置了Nutch和Solr，它们已经启动。我正在使用Solr为Nutch爬行的文档建立索引。但是，两者之间的通信（linkdb命令）失败。我发现了类似的线程，但是没有一个解决方案对我有用。类似线程（Nutch job failing when sending data to Solr）
我通过以下信息设置了配置文件：https://www.cs.toronto.edu/~muuo/blog/build-yourself-a-mini-search-engine/
版本： Nutch 1.14（https://archive.apache.org/dist/nutch/1.14/apache-nutch-1.14-bin.tar.gz） Solr 6.6（http://mirror.dsrg.utoronto.ca/apache/lucene/solr/6.6.5/solr-6.6.5.tgz）
我已经尝试使用Nutch Wiki中给出的https://github.com/apache/nutch/blob/master/conf/schema.xml中最近的schema.xml文件。
我从以下代码开始
nutch/bin/crawl -i -D solr.server.url=http://localhost:8983/solr/nutch -s nutch/urls/ Crawl 2
以
