--------------------------------------------
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.
