java - org.apache.solr.common.SolrException : Bad Request Bad Request request: http://localhost:8080/solr/update? wt=javabin&version=2

Question

请大家帮帮我 我正在尝试使用 NUTCH 抓取网站，但它给了我错误“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/* ”，并且使用 NUTCH 1.5.1 和 SOLR 3.6.1 以及 jdk java-7-openjdk-i386 和 ubuntu 12.04。

在 NUTCH/log 文件夹中存在的 hadoop.log 中显示以下内容:

在 Solr 中我没有找到任何日志文件。

请帮我解决这个问题，我真的很困惑。

Answer 1

您的日志说明了问题所在: Missing solr core name in path

您的请求的 Solr 核心名称应在 /solr/ 之间和/update?wt=...

类似这样的事情: 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
