Description

curl --netrc-file ~/.netrc -X POST http://localhost:8983/api/cores -H 'Content-Type: application/json' -d '
  {
    "create": {
      "name": "test_notes",
      "numShards": 1,
      "replicationFactor": 1    }
  }
'

Produces this error:

{
  "responseHeader":{
    "status":400,
    "QTime":3},
  "error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.core.SolrResourceNotFoundException"],
    "msg":"Error CREATEing SolrCore 'test_notes': Unable to create core [test_notes] Caused by: Can't find resource 'solrconfig.xml' in classpath or '/app/solr/server/solr/test_notes'",
    "code":400}}

I see the same error when I use `config:solrconfig.xml` in the curl call. This is the content of my `solr_home/server/solr` folder.

❯ ls ~/solr/server/solr/configsets/
_default  sample_techproducts_configs

This is the java code that's running solr:

 /app/jdk-11.0.1/bin/java -server -Xms512m -Xmx512m -XX:+UseG1GC -XX:+PerfDisableSharedMem -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=250 -XX:+UseLargePages -XX:+AlwaysPreTouch -XX:+ExplicitGCInvokesConcurrent -Xlog:gc*:file=/home/linuxuser/solr/server/logs/solr_gc.log:time,uptime:filecount=9,filesize=20M -Dsolr.jetty.inetaccess.includes= -Dsolr.jetty.inetaccess.excludes= -Dsolr.log.dir=/home/linuxuser/solr/server/logs -Djetty.port=13745 -DSTOP.PORT=12745 -DSTOP.KEY=solrrocks -Dhost=localhost -Duser.timezone=UTC -XX:-OmitStackTraceInFastThrow -XX:OnOutOfMemoryError=/home/linuxuser/solr/bin/oom_solr.sh 13745 /home/linuxuser/solr/server/logs -Djetty.home=/home/linuxuser/solr/server -Dsolr.solr.home=/app/solr/server/solr/ -Dsolr.data.home= -Dsolr.install.dir=/home/linuxuser/solr -Dsolr.default.confdir=/home/linuxuser/solr/server/solr/configsets/_default/conf -Xss256k -Dsolr.httpclient.builder.factory=org.apache.solr.client.solrj.impl.PreemptiveBasicAuthClientBuilderFactory -Dbasicauth=linuxuser:SolrForCedarU54 -Djava.security.manager -Djava.security.policy=/home/linuxuser/solr/server/etc/security.policy -Djava.security.properties=/home/linuxuser/solr/server/etc/security.properties -Dsolr.internal.network.permission=* -DdisableAdminUI=false -Dsolr.log.muteconsole -jar start.jar --module=http --module=requestlog --module=gzip

My questions are:

a. What am I doing wrong?
b. Why is Solr trying to find a solrconfig.xml in a directory that it has not yet created (`test_notes`)?
c. What is this `classpath` Solr is referring to?

Also, I have symlinked `/app/solr` to `~/solr`. I presume that won't cause a problem?
