Hi Eric, You can use the CloudSolrServer which is zk aware and does a reasonable amount of intelligent stuff for you. http://lucene.apache.org/solr/4_5_0/solr-solrj/org/apache/solr/client/solrj/impl/CloudSolrServer.html
All it takes is the zk host address so you would not have to worry about tracking what nodes host what collection.
