Zheng Hu commented on HBASE-20138:
----------------------------------
If only allow the rs which has the region online currently to update the
region's last pushed sequence id, so no conflicts will happen ?
> Find a way to deal with the conflicts when updating replication position

> Project: HBase
> Issue Type: Sub-task
> Reporter: Duo Zhang
> Assignee: Zheng Hu
> Priority: Major
>
> For now if a table is not created with SERIAL_REPLICATION_SCOPE and later
> converted to SERIAL_REPLICATION_SCOPE , then we may have multiple replication
> sources which replicate the different ranges for the same region and update
> the queue storage concurrently. This will cause problem if the lower range
> finish at last since the replication position will be wrong...
> Need to find a way to deal with this.
