> This is the real fix to HBASE-3773, we need to stop creating so many connections to ZK. Currently the problem is that we don't want to mix connections between the region server, a client, and whatever else in a JVM that requires talking to ZK. The current situation is a (non-intended) tradeoff of worse usability for easier unit testing.
> Another thing to take into account is that a client or a region server needs to be able to talk to more than one ensemble at the same time (CopyTable, replication are examples).
