RE: weird error for accessing solr
A little update. For the client machine where solr admin page behaves differently, it turns out that the requests on the page like */admin/* were never served. I think it is related to the server setting that might prevent these urls with "/admin/" from being sent. In essence, it is not a solr issue.

RE: weird error for accessing solr
Alex, I tried to curl http://solr.server:8983/solr/ and got different results from different machines. I also did shift-reload which gave me the same result. So it does not seem to be a browser cache issue. I also shut down solr and tried to access it. It gave connection failure error for both client machines. So it is not the case they are connecting to different instances. A bit more information, for the machine that see solr correctly, it is a laptop/desktop for developers. The other machine which solr admin page showed solrcloud with core initialization error, is a dev/qa server. Any help will be greatly appreciated.

RE: weird error for accessing solr
No the solr was not restarted as SolrCloud. We see solr from one computer and all cores are available for query, but from another computer, it shows the admin page as solrcloud with errors on the page. All the links on the left nav do not work either. -Original Message- From: Alexandre Rafalovitch Sent: Tuesday, September 18, 2018 2:39 PM To: solr-user Subject: Re: weird error for accessing solr Sounds like your Solr was restarted as a SolrCloud, maybe by an automated script or an init service? If you created a core in a standalone mode and then restart the same configuration in a SolrCloud mode, it would know that you have those collections/cores, but will not be able to find any configuration files (because it will expect them in ZooKeeper, not on disk).

Re: weird error for accessing solr
Sounds like your Solr was restarted as a SolrCloud, maybe by an automated script or an init service? If you created a core in a standalone mode and then restart the same configuration in a SolrCloud mode, it would know that you have those collections/cores, but will not be able to find any configuration files (because it will expect them in ZooKeeper, not on disk).
