David Smiley created SOLR-15312:
-----------------------------------
Summary: v2 api: core creation, config vs configSet params
Key: SOLR-15312
URL: https://issues.apache.org/jira/browse/SOLR-15312
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: v2 API
Reporter: David Smiley
I tried to follow our [ref guide's
instructions|https://solr.apache.org/guide/8_8/config-sets.html#configsets-in-standalone-mode]
on how to create a core with a certain configSet using the V2 API. It has me
specify the "configSet" param. But it does not work... the generated
core.properties file contains the "configSet" reference and unexpectedly a
"config" reference. Since I have a normally named solrconfig.xml, this fails
core creation.
I figured out the bug is here:
https://github.com/apache/solr/blob/4e90e48ac29ee38662c04fcf7815d5170ceb2669/solr/solrj/src/java/org/apache/solr/client/solrj/request/CoreApiMapping.java#L43
which maps "config" to "configSet". But these are distinct things. If you
were to [introspect the core creation
api|http://localhost:8983/api/cores/_introspect?command=create] you would see
these two parameter definitions:
{code}
"config":{
"type":"string",
"description":"Name of the config file (i.e., solrconfig.xml)
relative to instanceDir. If you are using the default name (solrconfig.xml),
you do not need to define the config file name."},
"configSet":{
"type":"string",
"documentation":"https://lucene.apache.org/solr/guide/config-sets.html";,
"description":"The name of a config set to use. The config set
must already exist. The solr.xml file defines the location of the configset
base directory, and configuration files can be shared between cores by defining
sub-directories. The files in the named configSet will be used for the schema
and config properties instead of defining them explicitly."},
{code}
There is also a "schema" param for the file name of the schema.
I see two courses of action. One keeps the current introspect API and is
trivially implemented at the line of code I showed, replacing the mapping with
null. Or, use "config" for the configSet, and rename "config" and "schema"
params to "configFile" and "schemaFile" respectively (or some other names).
The point of the latter is to align SolrCloud with standalone API on the
semantics of what "config" refers to.
