             Summary: WALPrettyPrinter: Additional useful infos to be printed by wal printer tool, for debugability purposes
                 Key: HBASE-21185
                 URL: https://issues.apache.org/jira/browse/HBASE-21185
             Project: HBase
          Issue Type: Improvement
            Reporter: Wellington Chevreuil
            Assignee: Wellington Chevreuil


*WALPrettyPrinter* is very useful for troubleshooting wal issues, such as faulty replication sinks. An useful information one might want to track is the size of a single WAL entry edit, as well as size for each edit cell. Am proposing a patch that adds calculations for these two, as well an option to seek straight to a given position on the WAL file being analysed.
