database - 无法访问 jetty 上的/solr

Question

我正在尝试按照我在 solr 1.4 到 solr 3.5 中的模式运行 solr，当我将核心和模式添加到 3.5 时:发现“500”错误

HTTP ERROR 500

Problem accessing /solr/. Reason:

    Severe errors in solr configuration.

Check your log files for more detailed information on what may be wrong.

If you want solr to continue after configuration errors, change: 

 <abortOnConfigurationError>false</abortOnConfigurationError>

in solr.xml

我的核心配置如下:

  <cores adminPath="/admin/cores">
    <core name="geoplanet" instanceDir="solr-geoplanet"/>
<property name="dataDir" value="solr-geoplanet/data" />

从 solr1.5 迁移到 solr3.1 是否需要任何额外的配置更改？

您需要做的就是按照 https://issues.apache.org/jira/browse/SOLR-1007 中提供的方式对属性值进行硬编码
