             Summary: Use existing private field in DistributedUpdateProcessor
                 Key: SOLR-11511
                 URL: https://issues.apache.org/jira/browse/SOLR-11511
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: SolrCloud
    Affects Versions: master (8.0)
            Reporter: Gus Heck


The DistributedUpdateProcessor has a private instance field called coreDesc. It is used in a few places, but most code navigates to CoreDescriptor from the request object instead. 

The fundamental question of this ticket, is this: is there any reason to distrust this field and do the navigation directly (in which case maybe we get rid of the field instead?) or can we trust it and thus should use it where we can. Since it is a private field only ever updated in the constructor, it's not likely to be changing out from under us. The request from which it is derived is also held in a private final field, so it very much looks to me like this field should have been final and should be used.

This might or might not be a performance gain (depending on whether or not the compiler can optimize away something like this already), but it will be a readability and consistency gain for sure.

Attaching patch to tidy this up shortly...
