----------------------------------------------------------------
Yeah, we checked the phase 2 design of read replica, there will be no out of
order for meta replica replication. It will only be used for region location
for hbase client, not something else. For master's view of meta, it can always
talk with primary meta replica (just like there is no replica for meta).
Most of logic/foundation has been laid out by phase 2 of read replica, we are
trying to put some glue logic for meta and some optimizations for this special
case.

> Based on the current doc, memstore replication is not enabled for meta
> replica. Memstore replication will be a good improvement for meta replica.
> Create jira to track this effort (feasibility, design, implementation, etc).
