             Summary: HBase Backup/Restore Phase 1: Custom WAL archive cleaner
                 Key: HBASE-14036
                 URL: https://issues.apache.org/jira/browse/HBASE-14036
             Project: HBase
          Issue Type: Task
            Reporter: Vladimir Rodionov
            Assignee: Vladimir Rodionov
             Fix For: 2.0.0


Custom WAL archive cleaner (BackupLogCleaner).  We need to keep WAL files in archive until
they either get copied over to backup destination during an incremental backup or full backup
(for ALL tables) happens. This is tricky, but is doable. Backup-aware WAL archiver cleaner
should consult hbase:backup to determine if WAL file is safe to purge.
