Subject [jira] [Commented] (SOLR-13553) Node level custom RequestHandlers
Date Tue, 02 Jul 2019 18:27:00 GMT

    [ https://issues.apache.org/jira/browse/SOLR-13553?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16877223#comment-16877223
] 

Jan Høydahl commented on SOLR-13553:
------------------------------------

Agree that clusterprops was not intended as a place to dump any and config on the cluster
level, even if it has a REST API. 

Perhaps a new clusterconfig.json or add an edit api for solr.xml (which can live in zk btw)?

Can you mention a few examples of new handlers that will use this mechanism?
