OK, I think this is the root of your problem: bq: Everything was setup using the - now deprecated - tags <cores> and <core> inside solr.xml.
There are a bunch of ways this could go wrong. I'm pretty sure you have something that would take quite a while to untangle, so unless you have a _very_ good reason for making this work, I'd blow everything away. First stop Zookeeper and all your Solr instances. If you're using an external Zookeeper shut if off and, 'rm -rf /tmp/zookeeper'. If using embedded, you can remove zoo_data under your SOLR_HOME. Completely remove all of your cores as in 'rm -rf corename' on all the nodes. Nuke the entries in solr.xml and use the "cloud friendly" solr.xml, I'd just copy the one in '...4.10/solr/example/solr'''. You get the idea. Or you can brute-force this and just remove all of Solr and re-install 4.10.3. OK, now use the Collections API to create your collection, see: https://cwiki.apache.org/confluence/display/solr/Collections+API and go from there (don't forget to push your configs to Zookeeper first) and go from there. Note that when I suggest you uninstall/reinstall Solr it's simply because that's conceptually easier, of course you can spend some time untangling things with your existing setup, but I really question whether it's worth the effort.
