请大家帮帮我我正在尝试使用 NUTCH 抓取网站,但它给我错误“java.io.IOException: Job failed!
”
我正在运行此命令“bin/nutch solrindex http://<host name>:8080/solr/ crawl/crawldb -linkdb crawl/linkdb crawl/segments/*
”并且我正在使用 NUTCH 1.5.1 和 SOLR 3.6.1 以及 jdk java-7-openjdk-i386 和 ubuntu 12.04。
在 hadoop.log 存在于 NUTCH/log 文件夹中显示以下内容:

在 Solr 中我没有找到任何日志文件。
请帮我解决我真正遇到的问题。
最佳答案
您的日志说明了问题所在: Missing solr core name in path
您的请求应在 /solr/
之间具有 Solr 核心名称和 /update?wt=...
是这样的: http://<host name>:8983/solr/<core_name>/update?wt=javabin&version=2
也许您应该将核心名称添加到您的 nutch 命令 URL 中
