What you describe is more like the rsync tool, which isn't what HBase replication is doing at all. Replication works with log shipping, and only copies data when it reads it from a log, there's no proactive thread that checks for differences between two clusters and that copies the missing pieces.
Is my understanding of your understanding of replication correct?
