我将schema.xml从nutch / conf文件夹下载到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我用solr / dist /文件夹中的solr-solrj-3.6.2.jar更改了nutch / lib文件夹中的solr-solrj-3.4.jar文件...

我可以展示我的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"/>
    <field dest="boost" source="boost"/>
    <field dest="digest" source="digest"/>
    <field dest="tstamp" source="tstamp"/>
    <field dest="id" source="url"/>
    <copyField source="url" dest="url"/>
</fields>
<uniqueKey>id</uniqueKey>
</mapping>

感谢您的任何建议。

使用Nutch配置（nutch-default.xml）设置临时目录的路径：

<property>
 <name>mapred.temp.dir</name>
 <value>/tmp</value>
 <description>A shared directory for temporary files.</description>
</property>

<强>参考

• Nutch Configuration Files

• MapReduce Default Configuration

• Configure Tomcat's File and Webapp Paths

• Specify temp/working directory for crawl

• Environment variable to control java.io.tmpdir?
