> HBase snapshots support in VerifyReplication tool to reduce load on live

> 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
