在apach solr（trunk）中集成apache nutch（版本1.2）的问题 - 得到了solr异常

标签： solr integration nutch

我已配置solrindex-mapping.xml（nutch）并配置了我的solr schema.xml和solrconfig.xml。两者都在单次运行时运行良好，但如果我使用bin/nutch solrindex ...，我会得到一个例外：

org.apache.solr.common.SolrException: Document [null] missing required field: id

我在所有配置文件中配置了id。在solrindex-mapping.xml，它从url映射到id，在schema.xml solr我也配置了ID。我不知道出了什么问题。我将一些日志记录输出添加到org.apache.nutch.indexer.solr.SolrWriter.java。当读取字段添加到SolrInputDocument时，我在这些行添加一个loginfo。构建和运行后的结果是：

2010-09-11 21:31:06,326 INFO  solr.SolrWriter - write()
2010-09-11 21:31:06,327 INFO  solr.SolrWriter - Key: segment, value: 20100911212934
2010-09-11 21:31:06,327 INFO  solr.SolrWriter - Key: boost, value: 1.0
2010-09-11 21:31:06,327 INFO  solr.SolrWriter - Key: digest, value: bc315927b7c01c7a2905d5b6872bc35b
2010-09-11 21:31:06,327 INFO  solr.SolrWriter - close()

您将只看到3个读取字段O_o。有谁知道我的配置是否有问题？ 我需要快速运行的nutch，因为我目前正在写我的学士论文：/ （关于本地网络异构数据源的信息集成）

最好的问候 marcel =）

Nutch 1.2不适用于Solr主干...

来自Nutch邮件列表（原始帖子here）...

  

大家都知道1.2是否适用于当前的Solr主干？

     

它没有，它使用Solr 1.4.x. Solr trunk使用不兼容的API。
