> Key: SOLR-10054
> URL: https://issues.apache.org/jira/browse/SOLR-10054
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Affects Versions: master (7.0), 6.4.0
> Reporter: Shawn Heisey
> Assignee: Andrzej Bialecki

>
> The new 6.4.0 version includes some significant changes having to do with
> metrics. These changes have broken core swapping. Will attach some
> screenshots.
> For the screenshots that I will attach, I started Solr directly from the
> 6.4.0 download on Windows 7 (bin\solr start). Then I created a "foo" core
> and a "bar" core, each from a different configset, using the bin\solr command.
> * Screenshot 1: you can see the two cores in CoreAdmin.
> * Screenshot 2: Attempting to swap the cores, an error message appears about
> a metric already existing for the ping handler.
> * Screenshot 3: Clicking somewhere else and then back to CoreAdmin shows
> that both cores have the same name -- bar.
> * If Solr is stopped and then started back up, the admin UI looks like
> screenshot 1 again -- the change that caused two cores with the same name
> only took place within the running Solr and did not update core.properties
> files.
