             Summary: Find a way to deal with the conflicts when updating 
replication position
                 Key: HBASE-20138
                 URL: https://issues.apache.org/jira/browse/HBASE-20138
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang

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.
