Although it would be *possible* to do this, it seems like a huge amount of overhead (jetty and Solr) just to get zookeeper running. If you plan to actually put Solr indexes on that node, overhead would be less of a problem, but there's another reason to have zookeeper in an entirely separate process even if you're sharing hardware: If you're running zookeeper as part of Solr, you can't shut down or restart Solr without affecting the zookeeper ensemble and possibly forcing an election. If zookeeper is a separate process, then restarting Solr cannot cause disruption within the ensemble. Thanks, Shawn
