SOLR uniqueKey with solr.UUIDField

Question

Trying to use solr.UUIDField to generate a uniqueKey field.

<fieldType name="uuid" class="solr.UUIDField" indexed="true" />


<field name="uid" type="uuid" indexed="true" stored="true" default="NEW" />

<uniqueKey>uid</uniqueKey>

But for some reason its not working.

Error message:

{msg=SolrCore 'db' is not available due to init failure: uniqueKey field (null) can not be configured with a default value (NEW). Schema file is .\example-DIH\solr\db\schema.xml,trace=org.apache.solr.common.SolrException: SolrCore 'db' is not available due to init failure: uniqueKey field (null) can not be configured with a default value (NEW).

I tried to remove following but then nothing is indexed:

<searchComponent name="elevator" class="org.apache.solr.handler.component.QueryElevationComponent" >
    <!-- pick a fieldType to analyze queries -->
    <str name="queryFieldType">string</str>
    <str name="config-file">elevate.xml</str>
</searchComponent>

To configure the uuid field in solr 4.6, you may need the following configurations

<!--schema.xml-->

<fieldType name="uuid" class="solr.UUIDField" indexed="true" />

<field name="id" type="uuid" indexed="true" stored="true" required="true" />

<uniqueKey>id</uniqueKey>

<!--solrconfig.xml-->
<updateRequestProcessorChain name="uuid">
    <processor class="solr.UUIDUpdateProcessorFactory">
      <str name="fieldName">id</str>
    </processor>
    <processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>


 <requestHandler name="/update" class="solr.UpdateRequestHandler">
       <lst name="defaults">
         <str name="update.chain">uuid</str>
       </lst>
</requestHandler>

Here is a link to a sample configuration that works for me : https://gist.github.com/leoh/8967328

For your second error "init failure:" you need to modify uid in elevate.xml file. The default path to elevate file is

@ SOLR_HOME\example\example-DIH\solr\solr\conf 

probably your path to that file may be different.

If you want to know where exactly in elevate.xml file then Please attach your elevate.xml file.
