Couple of times I faced this issue when firewall "Endpoint security" was on. Once I disabled it then it started working.
Also for creating collection, I usually do in the following way, upconfig the configuration to zookeeper using the command bin/solr zk upconfig -n collection1_configs -z srv-nl-com12:2181 -d collection1_configs then for creating collection use HTTP command ( REST API ) http://srv-nl-com13:8983/solr/admin/collections?action=CREATE&name=collection1&numShards=1&replicationFactor=2&maxShardsPerNode=2&collection.configName=collection1_configs This works fine for us... Hope this helps... -- View this message in context: http://lucene.472066.n3.nabble.com/can-t-create-collection-using-solrcloud-tp4338092p4338135.html Sent from the Solr - User mailing list archive at Nabble.com.
