Can't create new Solr core caused by can't find resource 'solrconfig.xml'

I just installed Solr and want to create a new core, but getting this error:
org.apache.solr.common.SolrException: 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'
I was trying to add it using the interface:
I hope somebody can help me out.
The option to create a new core in the Admin web page that you are using is a bit misleading, that option assumes you already have folders with some of the required data.
If you have access to the terminal on the machine where Solr is running you can easily create a core with a command like this:
$ cd ~/solr-8.4.1/bin
$ ./solr create -c name-of-your-new-core

Indexing problem with SOLR (MultiMaxScoreQParserPlugin)

I'm trying to integrate SOLR with Hybris but both of them are running on Kubernetes as a diffferent pod.
If I'm trying indexing SOLR on Hybris, it throws the error below;
ERROR [BackofficeLO-47] (000001JT) [SolrStandaloneSearchProvider] Error from server at http://10.10.100.181:34324/solr: Error CREATEing SolrCore 'master_backoffice_backoffice_product_flip': Unable to create core [master_backoffice_backoffice_product_flip] Caused by: de.hybris.platform.solr.search.MultiMaxScoreQParserPlugin
org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error from server at http://10.10.100.181:34324/solr: Error CREATEing SolrCore 'master_backoffice_backoffice_product_flip': Unable to create core [master_backoffice_backoffice_product_flip] Caused by: de.hybris.platform.solr.search.MultiMaxScoreQParserPlugin
I guess somethings wrong with SOLR "deafult" indexing directory.
Solr is running as process like below inside the pod;
solr#solr-fsd33wdf-qteg:/opt/solr-8.5.2$ ps -ef | grep solr
solr 10 1 0 Jun23 ? 00:15:55 /usr/local/openjdk-11/bin/java -server -Xms512m -Xmx512m -XX:+UseG1GC -XX:+PerfDisableSharedMem -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=250 -XX:+UseLargePages -XX:+AlwaysPreTouch -Xlog:gc*:file=/var/solr/logs/solr_gc.log:time,uptime:filecount=9,filesize=20M -Dsolr.jetty.inetaccess.includes= -Dsolr.jetty.inetaccess.excludes= -Dsolr.log.dir=/var/solr/logs -Djetty.port=8983 -DSTOP.PORT=7983 -DSTOP.KEY=solrrocks -Duser.timezone=UTC -Djetty.home=/opt/solr/server -Dsolr.solr.home=/var/solr/data -Dsolr.data.home= -Dsolr.install.dir=/opt/solr -Dsolr.default.confdir=/opt/solr/server/solr/configsets/_default/conf -Dlog4j.configurationFile=/var/solr/log4j2.xml -Xss256k -Dsolr.jetty.https.port=8983 -jar start.jar --module=http
So default confdir is /opt/solr/server/solr/configsets/_default/conf
If I'm check SOLR_HOME variable, it's different directory;
solr#solr-f575dcfdf-qtnpg:/opt/solr-8.5.2$ echo $SOLR_HOME
/var/solr/data
So, how can I change confdir to /var/solr/data ? I guess this is the problem here?
Thanks!
This page provides you with information on how to use the standalone setup. The ant configureSolrServer takes an argument of the path to the original Solr binary that you should download from here. This overwrites the files in the directory with the SAP Commerce specific setup. The MultiMaxScoreQParserPlugin is part of solr-hybris-components-<version_of_solr>.jar file, where the <version_of_solr> corresponds to the solr version your SAP Commerce is running on. Note that SAP Commerce also supports multiple Solr versions and it depends on what configuration you have.
You may then extend the default Solr docker image as provided here to have your setup running.

Cannot start indexing with solr in hybris 5.6

I tried to do indexing via HMC but it all get aborted with below error.
ERROR [coreLoadExecutor-4-thread-1] [CoreContainer] Failed to load file /hybris_extensions/hybris/config/solr/embedded/collection1/solrconfig.xml
ERROR [coreLoadExecutor-4-thread-1] [CoreContainer] Unable to create core: collection1
org.apache.solr.common.SolrException: Could not load config file /hybris_extensions/hybris/config/solr/embedded/collection1/solrconfig.xml
at org.apache.solr.core.CoreContainer.createFromLocal(CoreContainer.java:530)
I have started solr from hybris 5.6 in standalone mode and using linux machine.
hybris can run solr in standalone or embedded mode. When running in embedded mode, the configuration for SolR is created in the directory:
hybris/config/solr/embedded/
Therefore your hybris server needs the rights to write to this directory.

Solr 5: Adding a new Core fails out of the box

So I'm just playing around with Solr 5, but I tried to add a new Core through the Admin UI and the command line with:
bin/solr create -c new_core
But in both situations I get the following error:
new_core: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not load conf for core new_core: Error loading solr config from /Users/blah/lib/solr-5.3.0/server/solr/new_core/conf/solrconfig.xml
I started my Solr server using this:
bin/solr start
I'm following the docs here:
https://cwiki.apache.org/confluence/display/solr/Running+Solr
So what's the fix? How was this supposed to work out of the box given I assume there must be some template that the Admin UI uses when creating new cores?
The error is coming because there is no new_core configured in your setup.
Please perform the following steps:
mkdir /Users/blah/lib/solr-5.3.0/server/solr/core_name
echo "name=core_name" > /Users/blah/lib/solr-5.3.0/server/solr/core_name/core.properties
cp -r /Users/blah/lib/solr-5.3.0/server/solr/configsets/basic_configs/conf /Users/blah/lib/solr-5.3.0/server/solr/core_name/
Some important point to note:
core.properties and conf directory should be placed at same path.
conf directory will contain the schema.xml and solrconfig.xml files.

How to create new core in Solr 5?

Currently we are using Apache Solr 4.10.3 OR Heliosearch Distribution for Solr [HDS] as a search engine to index our data.
Now after that, I got the news about Apache Solr 5.0.0 release in last month. I'd successfully installed Apache Solr 5.0.0 version and now its running properly on 8983 port (means only running solr but unable to create core). In that UI, I'm unable to find the example core as well as schema or config files under it. So, I started creating new core as we create in old versions but unable to create one. Following is the error, I'm getting it:
Error CREATEing SolrCore 'testcore1': Unable to create core [testcore1] Caused by: Could not find configName for collection testcore1 found:null
Note: I also seen Cloud tab on (ie. http://localhost:8983/solr/) left side of Solr UI and also don't know how it works? Meaning I don't know the location of the schema.xml, solrconfig.xml files due to lack of example folder (Collection1) and how to update those files?
Is there any useful document or solution available to solve this error?
In Solr 5, creation of cores is supported by the bin/solr script provided in the distribution. Try
bin/solr create -help
for a quick introduction.
From the above help doc, you may find:
bin/solr create [-c name] [-d confdir] [-n configName] [-shards #] [-replicationFactor #] [-p port]
In Solr 5.4.0 , create new core using command from Solr-5.x.x folder (Solr Installation folder) like following,
$ bin/solr create -c <name>
See this documentation of Apache Solr 5.4 https://cwiki.apache.org/confluence/display/solr/Running+Solr
{SOLR_INSTALLATION}/server/solr/configsets\basic_configs\conf
you can find the example schema.xml and solrconfig.xml.
if you want to create the new core
{SOLR_INSTALLATION}/server/solr/{new core name} folder and create conf folder with required schema and solrconfig.xml and blank core.properties file.
you can find the examples for schema and config in
{SOLR_INSTALLATION}/example/example-DIH/solr
Create using the web interface
Go to bin directory and issue
./solr start -e cloud -noprompt
Which will start solr.
Go to http://localhost:8983
(this is assuming you are running on localhost)
Click on core admin and they "Add Core"
Use provided solr script with solr user privileges to create Solr cores, e.g.
cd /opt/solr
sudo -u solr ./bin/solr create -c testcore1
Run bin/solr --help for syntax guidance.
For any other issues, please check your Solr logs (e.g. /var/solr/logs/solr.log).
Related: SOLR-7826: Permission issues when creating cores with bin/solr as root user.
You can find your solrconfig.xml and schema.xml inside the collection directory.
Go to /usr/lib/ambari-infra-solr/server/solr and u will see a folder with same name as of collection and with schema and config files.
Inside the conf folder there will be a managed-schema file and other files that you have been searching for.
As for this error
Error CREATEing SolrCore 'testcore1': Unable to create core [testcore1] Caused by: Could not find configName for collection testcore1 found:null
This error must be coming when you are creating solr collection from UI.
For that go to location where solr.cmd is located and type the below code
./solr create -c -d -s -r
copy conf from solr/example/conf to solr/server/solr/.
