Shawn Heisey commented on SOLR-7894:
------------------------------------
At the moment you use the "Add Core" button, the core.properties file must NOT
exist. Adding the core will create that file. I think that these facts are
not well-documented.
The core.properties file is how the core is re-discovered when Solr is
restarted.

> Key: SOLR-7894
> URL: https://issues.apache.org/jira/browse/SOLR-7894
> Project: Solr
> Issue Type: Bug
> Affects Versions: 5.2.1
> Environment: CentOS 6.3
> Linux 2.6.32-504.23.4.el6.x86_64 #1 SMP Tue Jun 9 20:57:37 UTC 2015 x86_64
> x86_64 x86_64 GNU/Linux
> Reporter: Aaron Greenspan

> I have two Solr cores that I need to use. Their folders are already set up
> with appropriate permissions in the /solr subdirectory I'm using.
> Nevertheless, each time I start and stop Solr, the following ridiculous dance
> has to take place:
> 1. I go to the web interface on port 8983.
> 2. No cores are listed. I press the Add Core button.
> 3. I type in the name of the first of the two cores I want to re-add that was
> just there when the process was running previously in the "name" and
> "instanceDir" fields. I leave the other fields with their default values.
> 4. I press the blue "Add Core" button.
> 5. I get the following red error message: "Error CREATEing SolrCore '[core
> name]': Could not create a new core in /home/solr/server/solr/[core name]/as
> another core is already defined there".
> 6. I press the gray "Cancel" button.
> 7. I click "Java Properties" on the left side, or some other link in the
> administrative interface, just to get off the cores page.
> 8. I go back to the cores page.
> 9. The core is listed and is working fine.
> This is absurd.
> For one thing, I shouldn't have to do *anything*. Either by scanning the
> directory for the annoying-as-hell XML configuration files or some other
> method, it should remember the cores that were just there. But even assuming
> that's impossible for some reason (which it's not), I should not be getting a
> technically true but practically useless and misleading error message that
> suggests that adding the core *didn't* work when in fact it *did*.
