> Issue Type: Improvement
> Components: Replication
> Affects Versions: 2.0.0, 0.99.2, 1.0.0
> Reporter: Jianwei Cui
> Assignee: Mike Drob

>
> VerifyReplication will start the scanner for the table of peer cluster in
> Verifier#map(...). If the regions of the table in source cluster are empty,
> the Verifier#map(...) won't be invoked, so that the tool can not count the
> bad rows in the table of peer cluster. A possible improvement is to check
> whether the scanner for the table of peer cluster has been opened in
> Verifier#cleanup(...), and if not, open the scanner and count the rows only
> in the table of peer cluster as bad rows. Suggestions and discussions are
> welcomed.
