             Summary: In Solr LTR when adding a model referencing a non-existent feature the error message is very ambiguous
                 Key: SOLR-12367
                 URL: https://issues.apache.org/jira/browse/SOLR-12367
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: contrib - LTR
    Affects Versions: 7.3.1
            Reporter: Georg Sorst


When adding a model that references a non-existent feature a very ambiguous error message is thrown, something like `Model type does not exist org.apache.solr.ltr.model.{{LinearModel}}`

 

To reproduce, do not add any features and just add a model, for example by doing this:

 

{{curl -XPUT 'http://localhost:8983/solr/gettingstarted/schema/model-store' --data-binary '}}

{{{}}

{{  "class": "org.apache.solr.ltr.model.LinearModel",}}

{{  "name": "myModel",}}

{{  "features": [\{"name": "whatever" }],}}

{{  "params": \{"weights": {"whatever": 1.0}}}}

{{}' -H 'Content-type:application/json'}}

 

The resulting error message `Model type does not exist {{org.apache.solr.ltr.model.LinearModel` is extremely misleading and cost me a while to figure out the actual cause.}}

 

A more suitable error message should probably indicate the name of the missing feature that the model is trying to reference.
