> Core swapping doesn't work with new metrics changes in place
> ------------------------------------------------------------
> 
> 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 
> Attachments: SOLR-10054.patch, solr64coreswap1.png, solr64coreswap2.png, \
> solr64coreswap3.png 
> 
> 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.
