ok, I have fixed my issue. I needed to delete the config set first, so I did:
http://localhost:8983/solr/admin/configs?action=DELETE&name=timConfig , then I ran: ./bin/solr zk upconfig -n timConfig -d /home/tim/solr-7.3.0/server/solr/configsets/timConfig/ -z localhost:2181 , then tried creating the collection again with: http://localhost:8983/solr/admin/collections?action=CREATE&name=guardian_dev&numShards=2&replicationFactor=1&collection.configName=timConfig and it worked. So this posting is closed. Thanks -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
