Yeah...I need to get SOLR Cloud up and running. For some reason, I have yet to
succeed with it using an external Zookeeper for some reason. Ugghhh
Thanks for the confirmation!

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,
