That message is the clue. To figure out why there's a problem with CoreContainer, you're going to need to find and examine the solr.log file. If looking at the logfile doesn't give you any information you can understand, you'll probably need to share any ERROR or WARN logs in the file with us so we can pursue it further. Note that these messages are frequently quite long, and we will need all of it, not just the first line or two. Some of the information can't be properly interpreted without the Solr version, so include that too. Having access to the entire logfile would give us the best chance at determining what's wrong. Because the mailing list tends to eat all email attachments, you'll need to use a file sharing website or a paste website and provide a URL for us to access the file. If I had to guess what might be wrong, reading the instructions you're following, I am betting that there is no file named solr.xml in the defined solr home, and there is no solr.xml in zookeeper either. You might be able to get this working by copying solr.xml from the server/solr directory in the installation location to the defined solr home. Alternately, you could copy the file to zookeeper: https://lucene.apache.org/solr/guide/7_2/using-zookeeper-to-manage-configuration-files.html#preparing-zookeeper-before-first-cluster-start Thanks, Shawn
