> As of now VerifyReplicatin tool is running using normal HBase scanners. If you  want to run VerifyReplication multiple times on a production live cluster with large tables then it creates extra load on HBase layer. So if we implement snapshot based support then both in source and target we can read data from snapshots which reduces load on HBase
