----------------------------------
Summary: Remove unneeded distcp log cleanup after incremental
backups
Key: HBASE-27542
URL: https://issues.apache.org/jira/browse/HBASE-27542
Project: HBase
Issue Type: Improvement
Components: backup&restore
Affects Versions: 3.0.0-alpha-3
Reporter: Jarryd Lee
During the completion step of incremental backups, the
[TableBackupClient|https://github.com/apache/hbase/blob/2c3abae18aa35e2693b64b143316817d4569d0c3/hbase-backup/src/main/java/org/apache/hadoop/hbase/backup/impl/TableBackupClient.java#L343-L355]
ensures distcp logs are cleaned up. However,
[DistCp|https://github.com/apache/hadoop/blob/b87c0ea7ebde3edc312dcc8938809610a914df7f/hadoop-tools/hadoop-distcp/src/main/java/org/apache/hadoop/tools/DistCp.java#L465-L476]
already ensures that the metafolder, where the distcp logs are stored, is
cleaned up via a [shutdown
hook|https://github.com/apache/hadoop/blob/b87c0ea7ebde3edc312dcc8938809610a914df7f/hadoop-tools/hadoop-distcp/src/main/java/org/apache/hadoop/tools/DistCp.java#L439-L442].
The TableBackupClient cleanup method should be able to be safely removed.
