solr - 加载到 solr 时出现 Nutch 消息 "No IndexWriters activated"

Question

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 ”

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

Answer 1

确保插件 indexer-solr已经包括了。转到文件:conf/nutch-site.xml并在属性(property)plugin.includes添加插件，例如:

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

添加插件后 No IndexWriters activated - check your configuration在我的情况下，警告消失了。
