Sean Busbey commented on HBASE-18840:
-------------------------------------

the issue as I understand it is that meta has a superset of the information the 
RR cluster wants. the RR cluster wants to know "which of the files in the 
storage layer correspond to the table regions that are currently valid for the 
table?" and the primary cluster's meta includes e.g. mapping those regions to 
active RS instances.

what about relying a consistent snapshot of the table -> region -> hfiles 
mapping that gets written out periodically to storage?

> Add functionality to refresh meta table at master startup

> If a HBase cluster’s hbase:meta table is deleted or a cluster is started with 
> a new meta table, HBase needs the functionality to synchronize it’s metadata 
> from Storage.
