If I understand correctly you are trying to share a solr (cloud?) cluster between two different and remote data centers. As far as I know all the nodes of a solr cluster should see themselves and all of them should see the zookeeper ensemble. So we expect they are all in the same network. With SolrCloud clusters, when a solr node that receives a request can ask to another node to work for the response. I hope this helps to clarify why you should have two separate clusters. So, are you using a SolrCloud cluster?
