Re: Solr 5.2.1 - SolrCloud create collection, core is only loaded after restart
Hi, there was a problem with zookeeper and IPv6 that could be solved by using -Djava.net.preferIPv4Stack=true. Now, the core is correctly created, but I am wondering why I cannot see the core on the web interface, neither on the core admin screen nor in the Core Selector field. Only after restarting solr the core shows up on the web interface.

Re: Solr 5.2.1 - SolrCloud create collection, core is only loaded after restart
My _guess_ is that you're getting a cached page somehow and never getting to Solr at all when you don't see the new core. What happens if you look at the admin UI from another machine? Or perhaps a different browser? If you tail the Solr log when you are looking you should see the request when you try to see the new core, if you don't see a request come through then it's a caching issue... Or perhaps try issuing a core admin STATUS command? http://solr:port/solr/admin/cores?action=STATUS Best, Erick On Wed, Jul 8, 2015 at 6:14 AM, Jens Brandt bra...@docoloc.de wrote: Hi, there was a problem with zookeeper and IPv6 that could be solved by using -Djava.net.preferIPv4Stack=true.
