Subject [jira] [Commented] (SOLR-12526) Metrics History doesn't work with AuthenticationPlugin
Date Wed, 29 Aug 2018 07:50:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-12526?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16596052#comment-16596052
] 

Jan Høydahl commented on SOLR-12526:
------------------------------------

I have not tested the custom plugin but see from the code that it wants to handle inter node
requests, so then it is responsible for doing so in all cases. Michal, if you believe or later
find out that there are issues in Solr as well, feel free to re-open.

> Since solr 7.4.0 there is Metrics History which uses SOLRJ client to make http requests
to SOLR. But it doesnt work with AuthenticationPlugin. Since its enabled by default, there
are errors in log every time {{MetricsHistoryHandler}} tries to collect data.
