Erick Erickson commented on SOLR-4268:
--------------------------------------
Still an issue. The unload operation now removes the core.properties file
associated with the core, and there's no way to get it back. We might want to
retitle this to something like "revamp the core admin UI". Personally I'd be in
favor of only displaying the core admin API when _NOT_ connected to Zookeeper,
but that'd take some discussion as it has implications.
To support anything like an "unload" command we'd need some work, things like
1> standardize renaming core.properties rather than removing it. Say to
core.unloaded
2> get a list of all the potential cores with core.unloaded rather than
core.properties so we could get it back
3> whatever.....
I suppose wrapped around all of this is whether we want a core admin page at
all when we move to Zookeeper as "the one source of truth".....
> Admin UI - button to unload transient core without removing from solr.xml

> Reporter: Shawn Heisey
> Fix For: 4.9, 6.0

>
> The core "unload" button in the UI currently will completely remove a core
> from solr.xml. With the implentation of transient cores, there should be a
> way to ask Solr to unload a core without removing it entirely.
> This leads into a discussion about terminology. UNLOAD isn't a good
> single-word description for what it does. A case could be made for having
> REMOVE and DELETE actions for CoreAdmin, with confirmation prompts if you
> click on those buttons in the UI. DELETE could simply be an option on REMOVE
> - which I think you can actually currently do with UNLOAD.
> Another idea, not sure if it needs its own issue or is part of this one: If a
> core is mentioned in solr.xml but not actually loaded, it would be very cool
> if it were listed, but with a different background color to indicate the
> non-loaded state.
