> Key: SOLR-2333
> URL: https://issues.apache.org/jira/browse/SOLR-2333
> Project: Solr
> Issue Type: Bug
> Components: multicore
> Affects Versions: 3.1
> Reporter: Paul R. Brown
> Fix For: 3.1.1, 3.2, 4.0
>
>
> The core name during the persistence process is drawn from the core
> descriptor rather than the corecontainer, and the result is that renames are
> not persistent. It would be straightforward to change this by using the same
> style of manipulation of core name as used in the swap admin action.
> It would also be useful to change the access privileges of the name property
> of a CoreDescriptor so that admin handler implementations can manipulate core
> names directly.
