Subject [jira] [Updated] (SOLR-12367) When adding a model referencing a non-existent feature the error message is very ambiguous
Date Wed, 16 May 2018 21:48:00 GMT

     [ https://issues.apache.org/jira/browse/SOLR-12367?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Georg Sorst updated SOLR-12367:
-------------------------------
    Description: 
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.
