Shawn Heisey updated SOLR-12889:
--------------------------------
Description:
Solr isn't behaving quite correctly when performing CoreAdmin actions on cores
that exist, but failed to initialize.
* RELOAD works. That was made possible by SOLR-10021.
* UNLOAD works, and can even delete directories if asked to.
* RENAME works, but Solr must be restarted for the admin UI to reflect the new
name in the "SolrCore Initialization Failures" message.
* SWAP doesn't actually work, but returns a response that *LOOKS* like it
worked.
I didn't try the other actions, because it doesn't really make any sense to
allow those on a core that failed.
What I see as things that need to be checked or implemented when acting on
failed cores:
* SWAP
** Fail fast.
** OR make it work properly. If we choose this, adjust the core name in the
initFailures part of the STATUS response.
* RENAME
** Fail fast.
** OR make it work properly. If we choose this, adjust the core name in the
initFailures part of the STATUS response.
* UNLOAD
** This looks like it behaves correctly. Tried it with deleteInstanceDir=true
and it did wipe out the whole core.
* Other actions not already mentioned
** Fail fast
Something else to consider: Get rid of the initFailures part of the STATUS
response. List all cores, even those that failed. Include a boolean item in
the response to indicate whether initialization succeeded, and only list some
of the full information for a failed core. This would make implementing
SOLR-12863 easier.
