Missing processor in example update request processor chain?

[Walter Underwood <wu...@wunderwood.org>]

The documentation says that the default update request processor change invokes LogUpdateProcessorFactory, DistributedUpdateProcessorFactory, then RunUpdateProcessorFactory.

The example immediately below that, also in the default solrconfig.xml file, is missing  DistributedUpdateProcessorFactory. Is that a documentation bug or am I missing something?

<updateRequestProcessorChain name="dedupe">
  <processor class="solr.processor.SignatureUpdateProcessorFactory">
    <bool name="enabled">true</bool>
    <str name="signatureField">id</str>
    <bool name="overwriteDupes">false</bool>
    <str name="fields">name,features,cat</str>
    <str name="signatureClass">solr.processor.Lookup3Signature</str>
  </processor>
  <processor class="solr.LogUpdateProcessorFactory" />
  <processor class="solr.RunUpdateProcessorFactory" />
</updateRequestProcessorChain>
