well, I think that's because hbase or hadoop has nothing to do with vpn. It's completely independent. Just configure a VPN for the all machines in cluster A and cluster B (thus at least master A can access master B and vice versa*) and do the normal hbase stuff. E.g. cluster replication or exportSnapshot. It's not different than a setup for VPN and mysql, or cassandra etc. Best wishes, Wilm *) of course the vpn is much more complicate in a real world application, as the application server has to access the resp. masters, all machines in one cluster and the clients has to access the application servers etc..
