Question

使用solr设置多核（可能相关或不相关），我有一个工作测试系统。 solrconfig.xml住在/solr-4.4.0/example/multicore/expertise/conf，看起来基本上类似于多核的示例solrconfig文件，但以下几行除外：

<dataDir>/data/website_data/solr_cores/expertise</dataDir>

<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
  <lst name="defaults">
    <str name="config">/data/website_data/solr_cores/expertise/data-config.xml</str>
  </lst>
</requestHandler>

由于我需要一个支持语言的solr，我使用一些选择处理程序（以前handleSelect已经true）和一个新的updateRequestProcessorChain更新了solrconfig.xml。对solrconf.xml的更改如下所示：

<lib dir="${user.dir}/../contrib/analysis-extras/lucene-libs/" /><!-- relative to solrs 'example' directory -->
<lib dir="${user.dir}/../contrib/analysis-extras/lib/" />
<lib dir="${user.dir}/../dist/" regex="solr-langid-.*\.jar" />
<lib dir="${user.dir}/../contrib/langid/lib/" />    

<!-- required for language detection of input records -->
<updateRequestProcessorChain name="languages">
    <processor class="solr.LangDetectLanguageIdentifierUpdateProcessorFactory">
        <lst name="invariants">
            <str name="langid.fl">focus, expertise, platforms, partners, participation, additional</str>
            <str name="langid.whitelist">en,fr</str>
            <str name="langid.fallback">en</str>
            <str name="langid.langField">detectedlang</str>
            <bool name="langid.map">true</bool>
            <bool name="langid.map.keepOrig">false</bool>
        </lst>
    </processor>
    <processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>

<!-- uses language-detecting update.chain -->
<requestHandler name="/update" class="solr.UpdateRequestHandler">
    <lst name="invariants">
        <str name="update.chain">languages</str>
    </lst>
</requestHandler>

<requestDispatcher handleSelect="false"> <!-- ORIGINALLY FALSE -->

</requestHandler>

现在我收到错误： Can't find resource '/data-config.xml' in classpath or 'multicore/expertise/conf/', cwd=/solr-4.4.0/example</str>

数据路径没有改变。 data-config.xml文件存在于应该存在的位置，并且其权限是正确的。为什么我的原始solrconf.xml可以找到data-config.xml而我的新文件不能？

Answer 1

似乎solrconfig.xml中的语句顺序可以有所不同。在这种情况下，任何<lib/>声明都必须在其中一个（或可能是全部）声明之后：<luceneMatchVersion/>，<directoryFactory/ >，<dataDir>，<schemaFactory/>和{{1 }}。

最初，我的<updateHandler/>行紧接在开始<lib>标记之后。这恰好是他们在我工作的example中的位置。所以也许Java只是不合适而且我的solrconfig.xml没有问题。

我希望这有助于其他人。

编辑solrconfig.xml时，data-config.xml丢失
