No, that is not possible. This is one of the big advantages of SolrCloud over the old master-slave replication. If you create a new collection and tell it that you want a replicationFactor of 3, then 3 copies of that collection will exist on different machines in the cloud. There are no masters and no slaves -- one of those replicas will be elected as the leader. Thanks, Shawn
