             Summary: SyncTable logging improvements
                 Key: HBASE-24524
                 URL: https://issues.apache.org/jira/browse/HBASE-24524
             Project: HBase
          Issue Type: Improvement
            Reporter: Wellington Chevreuil
            Assignee: Wellington Chevreuil


While troubleshooting mismatches in replication deployment, SyncTable logging can provide some insights on what is diverging between two clusters. One caveat, though, is that it logs diverging row key as hexdecimal values, which is not so useful for operators trying to figure out which rows are mismatching, ideally, this info should be human readable, so that operators could have the exact value they could use for querying the tables with other tools, such as hbase shell.

Another issue is that while rows mismatches are logged as info, cell values mismatches are only logged as debug. In general, any of the mismatches would already be quite verbose, so ideally both should be logged in debug level.
