Description

With HBASE-2196 in place. Would be nice if we could control per CF to which peer(s) it is replicated.

Could have a new option REPLICATION_PEERS, which holds a , separated list of replication peers that this CF should be replicated to. If not given replicate to all slaves.

This list would need to written to each log entry (could reuse WALEdit.scopes for this), so we can decide in ReplicationSource who this entry should go to.

Let's discuss...
