Description

According to this documentation https://solr.apache.org/guide/solr/latest/configuration-guide/property-substitution.html, we should be able with the Collection API v2 CREATE, to define custom core properties and use them in the solrconfig.xml file

This is not working properly as, for example, if I try to define a "lib.path" property that I use in the solrconfig.xml of my collection, I get the following error:

curl -XPOST http://localhost:8983/api/collections -H 'Content-Type: application/json' -d '{"create": {"name": "MyCollection", "config": "Init", "numShards": 2, "replicationFactor":1, "property.lib.path":"/my/lib/path"}}' 

{
  "responseHeader":{
    "status":400,
    "QTime":738},
  "failure":{
    "127.0.0.1:8983_solr":"org.apache.solr.client.solrj.impl.BaseHttpSolrClient$RemoteSolrException:Error from server at null: Error CREATEing SolrCore 'MyCollection_shard1_replica_n3': Unable to create core [MyCollection_shard1_replica_n3] Caused by: No system property or default value specified for lib.path value:${lib.path}/Custom",
    "127.0.0.1:8983_solr":"org.apache.solr.client.solrj.impl.BaseHttpSolrClient$RemoteSolrException:Error from server at null: Error CREATEing SolrCore 'MyCollection_shard2_replica_n1': Unable to create core [MyCollection_shard2_replica_n1] Caused by: No system property or default value specified for lib.path value:${lib.path}/Custom"},
  "Operation create caused exception:":"org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Underlying core creation failed while creating collection: MyCollection",
  "exception":{
    "msg":"Underlying core creation failed while creating collection: MyCollection",
    "rspCode":400},
  "error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.common.SolrException"],
    "msg":"Underlying core creation failed while creating collection: MyCollection",
    "code":400}}

  

Doing the same with the Collection API v1 properly works:

curl -XGET "http://localhost:8983/solr/admin/collections?action=CREATE&name=MyCollection&collection.configName=Init&numShards=2&maxShardsPerNode=2&replicationFactor=1&property.lib.path=/my/lib/path"

{
  "responseHeader":{
    "status":0,
    "QTime":1419},
  "success":{
    "127.0.0.1:8983_solr":{
      "responseHeader":{
        "status":0,
        "QTime":1062},
      "core":"MyCollection_shard1_replica_n3"},
    "127.0.0.1:8983_solr":{
      "responseHeader":{
        "status":0,
        "QTime":1062},
      "core":"MyCollection_shard2_replica_n1"}}}
