---------------------------------------
Summary: Backup log collection can fail
Key: HBASE-29984
URL: https://issues.apache.org/jira/browse/HBASE-29984
Project: HBase
Issue Type: Bug
Components: backup&restore
Affects Versions: 2.6.4, 4.0.0-alpha-1, 3.0.0-beta-2
Reporter: Dieter De Paepe
Found during
[review|https://github.com/apache/hbase/pull/7582/changes/e1c25329acf26792bbf4faed98a44fab647e39d2#r2676601419]
of HBASE-29776.
The backup logic scans the logs and oldlogs:
* IncrementalBackupManager#getLogFilesForNewBackup
* (Introduced in HBASE-29776) FullTableBackupClient#execute
It assumes old logs are files under the "oldWals" folder.
However, there's a configuration key hbase.separate.oldlogdir.by.regionserver
that can change this behavior. When set to true, the old logs are stored in
directories under "oldWals". The backup code will error on this.
