[jira] [Commented] (SOLR-13218) MetricsHistoryHandler failes to
collect metrics in BasicAuthPlugin enabled setup
[ https://issues.apache.org/jira/browse/SOLR-13218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16760758#comment-16760758 ]
Jan Høydahl commented on SOLR-13218:
------------------------------------
This looks like SOLR-12526 but at that point we were not able to reproduce the error. Can you reproduce from a clean Solr download? If so, please provide all steps required.

> After some debugging it showed that the error only shows up during the (seemingly) periodic metrics collection on the leader node. The following stack is seen in this cases
> !image-2019-02-05-11-29-22-569.png!
> While trying to debug it a bit if this can be resolved by some additional settings - for which no solution was found - this method was also called from another location during collection creation where the authentication seems to work just fine
> !image-2019-02-05-11-30-33-948.png!
> So something in this chain must enable the correct authentication settings it seems.
> Appart from periodic error logs generally functionality seems to work but most likely something related to the cluster metrics is not fully working.
> Disabling basic authentication or setting ""blockUnknown": false" makes the issue disappear as expected.
