> As per parent jira, the cleanest way to add region replicas we think is to
> actually create one more region per replica per primary region. So for
> example, if a table has 10 regions with replication = 3, the table would
> indeed be created with 30 regions. These regions will be handled and assigned
> individually for AM purposes.
> We can add replicaId to HRegionInfo to indicate the replicaId, and use this
> to differentiate different replicas of the same region. So, primary replica
> would have replicaId = 0, and the others will have replicaId > 0.
> These replicas will share the same regionId prefix, but differ in an appended
> replicaId. The primary will not contain the replicaId so that no changes
> would be needed for existing tables.
> In meta, the replica regions are kept in the same row as the primary ( so for
> above example, there will be 10 rows in meta). The servers for the replicas
> are kept in columns like "server+replicaId".
