Kevin Geiszler updated HBASE-29826:
-----------------------------------
Description:
{{IntegrationTestContinuousBackupRestore}} is failing during the {{merge()}}
attempt because {{.backup.manifest}} is not in the expected location. The
manifest is still in the backup directory, but the actual path to the manifest
is incorrect.
For example, the correctly expected path is something like the following:
{noformat}
hdfs://localhost:60834/user/kgeiszler/test-data/7db8c206-5859-1fde-49d1-5e9bcadd8a62/backupIT/.tmp/backup_1768259498500/.backup.manifest
{noformat}
However, the actual path has the backup directory twice, such as the following:
{code:java}
hdfs://localhost:60834/user/kgeiszler/test-data/7db8c206-5859-1fde-49d1-5e9bcadd8a62/backupIT/.tmp/backup_1768259498500/backup_1768259498500/.backup.manifest
{code}
This may be happening because of the fs.rename() operation in
[MapReduceBackupMergeJob.java|https://github.com/apache/hbase/blob/HBASE-28957/hbase-backup/src/main/java/org/apache/hadoop/hbase/backup/mapreduce/MapReduceBackupMergeJob.java#L160].
This issue causes the following error:
{code:java}
