Solr : Index does not have an operational DataImportHandler defined

问题

I was trying to use DataImportHandler to index my MySQL Database using Solr in Cloud Mode, the following are the configurations it uses the _default configsets.

solr-7.3.0\server\solr\configsets\_default\conf\data-config.xml

# define data source
<dataConfig>
    <dataSource type="JdbcDataSource" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/expressg_dbkevinzeigler" user="root" password=""/>
    <document>
      <entity name="product"  
        pk="id_prd"
        query="SELECT id_prd, name_prd, description_prd FROM products_prd">
         <field column="id_prd" name="id"/>
         <field column="name_prd" name="name"/>       
      </entity>
    </document>
</dataConfig>

Added the following to: solr-7.3.0\server\solr\configsets\_default\conf\solrconfig.xml

<lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-7.3.0.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-7.3.0-extras.jar" />

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

Added the following to: solr-7.3.0\server\solr\configsets\_default\conf\managed-schema.xml

<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" /> 
    <field name="name" type="string" indexed="true" stored="true" multiValued="false" />

When I tried DataImport in Solr Admin on my current collection it says:

"The solrconfig.xml file for this index does not have an operational DataImportHandler defined!"

Anybody encounter the same?

回答1:

Please follow below steps to create our own configsets and create a collection using these configurations for Solr Cloud mode.

1 : Create a copy of default configurations, from your Solr installation directory.

sudo cp -R _default/ db_config

2 : Edit solrconfig.xml, DIHconfigfile.xml and schema.xml(managed_schema) files as per your requirement.

3 : Create a zip file of new configurations

(cd /usr/local/solr/server/solr/configsets/db_config/conf && zip -r - *) > db_config_set.zip

4 : Upload this configurations to ZooKeeper

curl -X POST --header "Content-Type:application/octet-stream" --data-binary @db_config_set.zip "http://your_host_ip:8983/solr/admin/configs?action=UPLOAD&name=db_config_set"

Once the upload is successful we could see our new configset while creating new collection in Solr Admin webpage. Creating custom configsets is useful while working on data import tasks.
