我一直在尝试各种事情，但无济于事。我对 Nutch/Solr 的配置基于此：
http://ubuntuforums.org/showthread.php?t=1532230
现在我已经启动并运行了 Nutch 和 Solr，我想使用 Solr 来索引爬网数据。Nutch 成功爬取了我指定的域，但在我运行命令将该数据传送到 Solr 时失败。这是命令：
bin/nutch solrindex http://solr:8181/solr/ crawl/crawldb crawl/linkdb crawl/segments/*
这是输出：

经过大量谷歌搜索后，我还尝试了另一个命令：
bin/nutch solrindex http://solr:8181/solr/ crawl/crawldb -linkdb crawl/linkdb crawl/segments/*
有了这个输出：

有没有人对如何克服这些错误有任何想法？
