---------------------------------------

It looks like an additional change is needed to cover VerifyReplication.  I'll post an updated patch shortly.

> When using CopyTable across two separate clusters, you can specify the ZK quorum for the destination cluster, but not much else in configuration overrides.  This can be a problem when the cluster configurations differ, such as when using security with different configurations for server principals.
> We should provide a general way to override configuration properties for the peer / destination cluster.  One option would be to allow use of a prefix for command line properties ("peer.property.").  Properties matching this prefix will be stripped and merged to the peer configuration.
