---------------------------------------
Summary: Incremental backup set does not correctly shrink
Key: HBASE-28568
URL: https://issues.apache.org/jira/browse/HBASE-28568
Project: HBase
Issue Type: Bug
Components: backup&restore
Affects Versions: 2.6.0, 3.0.0
Reporter: Dieter De Paepe
The logic in BackupAdminImpl#finalizeDelete does not properly clean up tables
from the incrementalBackupTableSet (= the set of backups to include in every
incremental backup).
This can lead to backups failing.
Minimal example to reproduce from source:
* Add following to `conf/hbase-site.xml` to enable backups:
{code:java}
<property>
<name>hbase.backup.enable</name>
<value>true</value>
</property>
<property>
<name>hbase.master.logcleaner.plugins</name>
<value>org.apache.hadoop.hbase.master.cleaner.TimeToLiveLogCleaner,org.apache.hadoop.hbase.master.cleaner.TimeToLiveProcedureWALCleaner,org.apache.hadoop.hbase.master.cleaner.TimeToLiveMasterLocalStoreWALCleaner,org.apache.hadoop.hbase.backup.master.BackupLogCleaner</value>
</property>
<property>
<name>hbase.procedure.master.classes</name>
<value>org.apache.hadoop.hbase.backup.master.LogRollMasterProcedureManager</value>
</property>
<property>
<name>hbase.procedure.regionserver.classes</name>
<value>org.apache.hadoop.hbase.backup.regionserver.LogRollRegionServerProcedureManager</value>
</property>
<property>
<name>hbase.coprocessor.region.classes</name>
<value>org.apache.hadoop.hbase.backup.BackupObserver</value>
</property>
<property>
<name>hbase.fs.tmp.dir</name>
<value>file:/tmp/hbase-tmp</value>
</property> {code}
