Nathan Neulinger commented on SOLR-5843:
----------------------------------------
In case it helps any - interesting result - I restarted the node with the error
this evening, and that bogus/broken collection spontaneously tried to recreate
itself on that node. No error msg in the log though - just shows as all
replicas being down.
I issued a delete against it and got this error:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<lst name="responseHeader"><int name="status">0</int><int
name="QTime">423</int></lst><lst name="failure"><str
name="10.220.16.191:8983_solr">org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException:Server
Error
request: http://10.220.16.191:8983/solr/admin/cores</str></lst>
</response>
but, it did clear it out... Not sure what state it was in. If y'all think this
is a goofy edge case that isn't likely to re-occur, go ahead and close this.
Either way though, I do think there should be a way to tell solr "clear your
errors and retry/refresh".

> Key: SOLR-5843
> URL: https://issues.apache.org/jira/browse/SOLR-5843
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.6.1
> Reporter: Nathan Neulinger
> Labels: cloud, failure, initialization
>
> Created collections with missing configs - this is known to create a problem
> state. Those collections have all since been deleted -- but one of my nodes
> still insists that there are initialization errors.
> There are no references to those 'failed' cores in any of the cloud tabs, or
> in ZK, or in the directories on the server itself.
> There should be some easy way to refresh this state or to clear them out
> without having to restart the instance.
