Duo Zhang commented on HBASE-29447: ----------------------------------- I think this is the cause of failure of TestIncrementalBackup? > WAL Archives Cause Incremental Backup Failures > ---------------------------------------------- > > Key: HBASE-29447 > URL: https://issues.apache.org/jira/browse/HBASE-29447 > Project: HBase > Issue Type: Bug > Components: backup&restore > Reporter: Hernan Gelaf-Romer > Assignee: Hernan Gelaf-Romer > Priority: Major > Labels: pull-request-available > > If a WAL file is rolled + archived during an incremental backup, we get a > FNFE and the backup process will fail. When we try to run the WalPlayer to > convert WAL files to HFiles, we run into the following error > > {code:java} > 2025-07-06 11:39:22.573 [pool-115-thread-1] ERROR > o.a.h.h.b.impl.TableBackupClient - Unexpected exception in > incremental-backup: incremental copy backup_1751801939412File > hdfs://venus-hb2-a-prod:8020/hbase/WALs/na1-real-weary-skink.iad02.hubinternal.net,60020,1751589560526/na1-real-weary-skink.iad02.hubinternal.net%2C60020%2C1751589560526.1751800206074 > does not exist. java.io.FileNotFoundException: File > hdfs://venus-hb2-a-prod:8020/hbase/WALs/na1-real-weary-skink.iad02.hubinternal.net,60020,1751589560526/na1-real-weary-skink.iad02.hubinternal.net%2C60020%2C1751589560526.1751800206074 > does not exist.{code} > > In order to make this more resilient, we could make sure to check the archive > directory for the missing WAL file if we run into this issue.
