Duo Zhang commented on HBASE-20046:

Design doc uploaded. Will backport to branch-2(actually merge back) if no 
objections. And then will finish HBASE-17918.

> When implementing HBASE-9465 we added two new families to meta table, one is 
> rep meta and the other is rep_position. In general I think rep_meta is OK to 
> put into meta table since it records the open and close sequence id for a 
> region, but for rep_position, I think it should be put into another system 
> table instead of meta table.
> This should be done before we finally release 2.0.0 or 1.5.0.
