Nutch 消息“未激活 IndexWriters"加载到 solr 时 [英] Nutch message "No IndexWriters activated" while loading to solr

问题描述

我已经按照 nutch 教程运行了 nutch 爬虫 http://wiki.apache.org/nutch/NutchTutorial 但是当我开始将它加载到 solr 时，我收到此消息，即未激活 IndexWriters - 检查您的配置"

I have run nutch crawler as per nutch tutorial http://wiki.apache.org/nutch/NutchTutorial but when i started loading it to solr i am getting this message i.e. "No IndexWriters activated - check your configuration"

bin/nutch solrindex http://localhost:8983/solr crawl/crawldb/ -dir crawl/segments/
Indexer: starting at 2013-07-15 08:09:13
Indexer: deleting gone documents: false
Indexer: URL filtering: false
Indexer: URL normalizing: false
**No IndexWriters activated - check your configuration**

Indexer: finished at 2013-07-15 08:09:21, elapsed: 00:00:07

推荐答案

确保包含插件 indexer-solr.转到文件:conf/nutch-site.xml 并在属性 plugin.includes 中添加插件，例如:

Make sure that the plugin indexer-solr is included. Go to the file: conf/nutch-site.xml and in the property plugin.includes add the plugin, for instance:

protocol-http|urlfilter-regex|parse-(html|tika)|index-(basic|anchor)|indexer-solr|scoring-opic|urlnormalizer-(pass|regex|basic)

protocol-http|urlfilter-regex|parse-(html|tika)|index-(basic|anchor)|indexer-solr|scoring-opic|urlnormalizer-(pass|regex|basic)

在添加插件后，No IndexWriters 被激活 - 检查您的配置警告在我的情况下消失了.

After adding the plugin the No IndexWriters activated - check your configuration warning disappeared in my case.
