---------------------------------------
Summary: Tracking of bulk-loads for backup does not work for
multi-root backups
Key: HBASE-28706
URL: https://issues.apache.org/jira/browse/HBASE-28706
Project: HBase
Issue Type: Bug
Components: backup&restore
Affects Versions: 2.6.0, 3.0.0, 4.0.0-alpha-1
Reporter: Dieter De Paepe
Haven't been able to test this yet, but I highly suspect that
IncrementalTableBackupClient#handleBulkLoad will delete records of the files
that were bulk loaded, even if those records are still needed for backups in
other backuproots.
I base this on the observation that the code for tracking which WALs should be
kept around, and backup metadata in general, are all tracked per individual
backuproot. But for the tracking of bulk uploads, this is not the case.
The result would be data loss (i.e. the bulk loaded data) when taking backups
across different backuproots.
