DIH を使用して mysql テーブルからデータをインポートしようとすると、このエラーが発生しました。

HTTP ERROR 500

Problem accessing /solr/dataimport. 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

ここに私のschema.xmlコードがあります

<fields>
    <field name="brands_test_id" type="string" indexed="true" stored="true" required="true" />
    <field name="categories_test_id" type="string" indexed="true" stored="true" required="true" />
  </fields>

また、data-config.xml には次のコードがあります。

<dataConfig>
    <dataSource type="JdbcDataSource" 
                driver="com.mysql.jdbc.Driver"
                url="jdbc:mysql://localhost/Webpage"      
                user="test" 
                password="test123"/>
    <document name="Products">
        <entity name="products" query="select brands_test_id,categories_test_id from products"
            <field name="brands_test_id" column="brands_test_id"
            <field name="categories_test_id" column="categories_test_id"
            <entity name="brands_test" query="select name from brands_test where id='$products.brands_test_id' "
                    <field name="brands_test" column="brands_test"/>
            </entity>
            <entity name="categories_test" query="select name from categories_test where id='$products.categories_test_id' "
                    <field name="categories_test" column="categories_test"/>
            </entity>
        </entity>
    </document>
</dataConfig>

ここにsolrconfig.xmlファイルがあります

<lib dir="../../../dist/" regex="apache-solr-dataimporthandler-\d.*\.jar" />

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

mysql-connector-java-3.1.14.tar.gz をダウンロードして解凍し、lib ディレクトリにコピーしました。ファイルディレクトリを正しく定義するアミ?これを修正するのを手伝ってください。
