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?
