----------------------------------

             Summary: improve VerifyReplication to compute BADROWS more accurately
                 Key: HBASE-10152
                 URL: https://issues.apache.org/jira/browse/HBASE-10152
             Project: HBase
          Issue Type: Improvement
          Components: Replication
    Affects Versions: 0.94.14
            Reporter: cuijianwei


VerifyReplicaiton could compare the source table with its peer table and compute BADROWS. However, the current BADROWS computing method might not be accurate enough. For example, if source table contains rows as {r1, r2, r3, r4} and peer table contains rows as {r1, r3, r4}, the BADROWS counter will be 3 because 'r2' in source table will make all the later comparisons fail. Will it be better if the BADROWS is computed to 1 in this situation? Maybe, we can compute the BADROWS more accurately in merge comparison?
