[jira] [Commented] (HBASE-20046) Reconsider the implementation for serial replication

["Duo Zhang (JIRA)" <ji...@apache.org>]

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...

> 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.
