Description

Steps To Reproduce

curl 'http://localhost:8983/solr/admin/cores?action=CREATE&name=new_core&instanceDir=new_core'

Expected Result

Create a core called "new_core".

Actual Result

Error CREATEing SolrCore 'new_core': Unable to create core [new_core] Caused by: Can't find resource 'solrconfig.xml' in classpath or '/var/solr/data/new_core/conf'

Somebody on solr-users tells me:

The CoreAdmin API requires that the instanceDir already exist, with a
conf directory inside it that contains solrconfig.xml, schema.xml, and
any other necessary config files.

Huh? Where is this magical knowledge mentioned in the API documentation?

Another user on the list serve says:

In fact, yes. The thing to remember here is that you're using a much
older approach that had its roots in the pre-cloud days.

The whole point of creating APIs is to abstract out details that the caller doesn't need to know, and yet this API requires an understanding of Solr's internal file structure and history of the project? I'm speechless.
