Duo Zhang commented on HBASE-20046:
-----------------------------------
And I'm afraid there will be something wrong with the region replica feature...
For rep_meta we use encoded region name as row key, but for other family meta,
we use the region name for default replica as row key...
> Reconsider the implementation for serial replication

> Key: HBASE-20046
> URL: https://issues.apache.org/jira/browse/HBASE-20046
> Project: HBase
> Issue Type: New Feature
> Components: Replication
> Reporter: Duo Zhang
> Assignee: Duo Zhang
> Priority: Major
> Fix For: 3.0.0, 2.1.0
>
>
> 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.
