Subject [jira] [Created] (HBASE-14112) VerifyReplication may fail to count bad rows when regions of table in source cluster are empty
Date Fri, 17 Jul 2015 03:26:04 GMT
cuijianwei created HBASE-14112:
----------------------------------

             Summary: VerifyReplication may fail to count bad rows when regions of table in
source cluster are empty
                 Key: HBASE-14112
                 URL: https://issues.apache.org/jira/browse/HBASE-14112
             Project: HBase
          Issue Type: Improvement
          Components: Replication
    Affects Versions: 0.99.2
            Reporter: cuijianwei
            Priority: Minor


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.
