    [ https://issues.apache.org/jira/browse/SOLR-6273?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14366070#comment-14366070 ] 

Greg Solovyev commented on SOLR-6273:
-------------------------------------

I am working on applying this patch to test cross datacenter replication. Unless I am misunderstanding the code, this patch assumes that replication for each collection is configured in solrconfig.xml. I.e without this section in a collection's solrconfig.xml file the collection won't get replicated:
<lst name="replica">
      <str name="zkHost">${zkHost}</str>
      <str name="source">source_collection</str>
      <str name="target">target_collection</str>
    </lst>

This means that CDCR won't work for collections created via collections API using a shared configset, because when collections are created via collections API with a configset, all collections will have identical solrconfig.xml and so there is no way to overwrite source and target parameters for each collection.
