So I was able to create the core using the cli not with root but with 'solr' user access. I sudo as solr in the box and ran the command to create the core
[solr@solr bin]$ ./solr create -c demo Copying configuration to new core instance directory: /var/solr/data/demo Creating new core 'demo' using command:http://localhost:8983/solr/admin/cores?action=CREATE&name=demo&instanceDir=demo { "responseHeader":{ "status":0, "QTime":2724}, "core":"demo"} This created the required file/folder structure under "/var/solr/data" It has all the default files, I need some direction to configure existing Cassandra keyspace into my solr core. I have already placed the Cassandra jdbc drivers into my Java/lib, I believe I should be using the 'DIH' example configs for getting the data into solr ?
