> Confusing logging during backup restore
> ---------------------------------------
>
> Key: HBASE-28408
> URL: https://issues.apache.org/jira/browse/HBASE-28408
> Project: HBase
> Issue Type: Bug
> Components: backup&restore
> Affects Versions: 2.6.0
> Reporter: Dieter De Paepe
> Assignee: Dieter De Paepe
> Priority: Minor
> Labels: pull-request-available
> Fix For: 2.6.0, 4.0.0-alpha-1, 3.0.0-beta-2
>
>
> Encountered this while experimenting with the backup/restore functionality.
> My setup was as follows:
> * Took several backups (Full1, inc2, inc3)
> * Changed an entry in the "lily_tenant_acme:LILY_SETTINGS" table
> * Attempt a restore (to test if my changed entry is reverted):
> {code:java}
> $ hbase restore -conf backup-conf.xml s3a://backuprestore-experiments/hbase
> backup_1709123740345 -t "lily_tenant_acme:LILY_SETTINGS" -m
> "lily_tenant_acme:LILY_SETTINGS-restored1" -o
> 24/02/28 16:15:41 WARN org.apache.hadoop.hbase.mapreduce.TableMapReduceUtil:
> The addDependencyJars(Configuration, Class<?>...) method has been deprecated
> since it is easy to use incorrectly. Most users should rely on
> addDependencyJars(Job) instead. See HBASE-8386 for more details.
> 24/02/28 16:15:58 WARN org.apache.hadoop.hbase.tool.LoadIncrementalHFiles:
> Skipping non-directory
> hdfs://hdfsns/user/lily/hbase-staging/bulk_output-lily_tenant_acme-LILY_SETTINGS-restored1-1709136941410/_SUCCESS
> 24/02/28 16:15:59 WARN
> org.apache.hadoop.hbase.backup.impl.RestoreTablesClient: Nothing has changed,
> so there is no need to restore 'lily_tenant_acme:LILY_SETTINGS'
> {code}
> Based on the final logging line, I presumed my restore operation had failed.
> After some investigation however, I found that this was not the case: my
> change was reverted as expected.
> Some code investigation learned me this log message is shown because I was
> restoring backup `inc3`, and there were no changes between `full1` and `inc3`.
> I suggest rephrasing this log message, and changing it to a INFO level.
