当我启动 solrindex 时，我有一个例外，
org.apache.solr.common.SolrException: Bad Request
这是 hadoop.log 文件内容

我认为我的 schema.xml 有问题，就是这样

我将 schema.xml 从 nutch/conf 文件夹处理到 solr/conf，现在我使用 nutch 1.6 solr 3.6.2 和 apache tomcat 6.0.36 ......我想我会帮助理解这个问题。我在 apahce 日志文件中没有任何错误... olso 我使用 solr/dist/ 文件夹中的 solr-solrj-3.6.2.jar 更改 nutch/lib 文件夹中的 solr-solrj-3.4.jar 文件...
我可以显示我的 solrindex-mapping.xml
<mapping>
<!-- Simple mapping of fields created by Nutch IndexingFilters
to fields defined (and expected) in Solr schema.xml.
Any fields in NutchDocument that match a name defined
in field/@source will be renamed to the corresponding
field/@dest.
Additionally, if a field name (before mapping) matches
a copyField/@source then its values will be copied to
the corresponding copyField/@dest.
uniqueKey has the same meaning as in Solr schema.xml
and defaults to "id" if not defined.
-->
<fields>
<field dest="content" source="content"/>
<field dest="title" source="title"/>
<field dest="host" source="host"/>
<field dest="segment" source="segment"/>
