我已经配置了（nutch）并solrindex-mapping.xml配置了我的solr 。两者都在单次运行中运行良好，但如果我使用我得到一个异常：schema.xmlsolrconfig.xmlbin/nutch solrindex ...

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

我已经id在所有配置文件中配置了。在solrindex-mapping.xml它映射url到solrid和 at 时schema.xml，我也配置了 id。我不知道怎么了。我将一些日志输出添加到org.apache.nutch.indexer.solr.SolrWriter.java. 当读取字段添加到 SolrInputDocument 时，我在这些行添加了一个 loginfo。编译运行后的结果是：

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()

您只会看到 3 个读取字段 O_o。有谁知道我的配置是否有问题？我需要跑得很快，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

Nutch 1.2 不适用于 Solr 主干...

来自 Nutch 邮件列表（此处为原始帖子）...

你们都知道 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。
