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 -- This message was sent by Atlassian JIRA (v6.3.15#6346)
