加载到solr时Nutch消息"没有IndexWriters激活"

Question

我按照nutch教程运行了nutch crawler http://wiki.apache.org/nutch/NutchTutorial但是当我开始将它加载到solr时我收到了这条消息,即" 没有激活IndexWriters - 检查你的配置 "

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

协议HTTP | urlfilter正则表达式| parse-(HTML | TIKA)|索引 - (基本|锚)|索引-solr的|记分OPIC | urlnormalizer-(传递|正则表达式|基本)

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