Solr 7.6 Creating Collection using ConfigSets, Errors

Solr7.6 Creating ConfigSet

Solr ConfigSets API provides rest end points for creating, listing, viewing, and deleting ConfigSets.  While trying to create a collection based on the ConfigSet created using the Rest Service as documented:

$ (cd solr/server/solr/configsets/sample_techproducts_configs/conf && zip -r - *) > myconfigset.zip

$ curl -X POST --header "Content-Type:application/octet-stream" --data-binary @myconfigset.zip "http://localhost:8983/solr/admin/configs?action=UPLOAD&name=myConfigSet"

results in the following error message:

ERROR: Failed to create collection 'tech' due to: {192.168.56.102:8983_solr=org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException:Error from server at http://192.168.56.102:8983/solr: Error CREATEing SolrCore 'tech_shard3_replica_n10': Unable to create core [tech_shard3_replica_n10] Caused by: The configset for this collection was uploaded without any authentication in place, and this operation is not available for collections with untrusted configsets.

The documentation says that functionality of uploading a configset is enabled by default, but can be disabled via a runtime parameter -Dconfigset.upload.enabled=false. Disabling this feature is advisable if you want to expose Solr installation to untrusted users (even though you should never do that!).

Instead of using the REST service for creating the configset, used the Solr's zkcli.sh file found under <SOLR_HOME>/server/scripts/cloud-scripts/, as shown below:

#!/bin/sh

SOLR_HOME=~/solr-7.6.0

ZK_HOST=wolf:2181,tiger:2181,lion:2181

CONF_NAME=tech

CONF_DIR=~/solr/tech/

$SOLR_HOME/server/scripts/cloud-scripts/zkcli.sh -z $ZK_HOST -cmd upconfig -confname $CONF_NAME -confdir $CONF_DIR

After executing the above command a Solr collection by the name tech as defined in the above script was successfully created.
