Backup has been successfully deleted but the backup root dir under /user/hbase dir still persists

hbase@cluster-name:~$ hdfs dfs -ls /user/hbase
Found 6 items
drwx------   - hbase hbase          0 2016-06-15 00:26 /user/hbase/.staging

drwxr-xr-x   - hbase hbase          0 2016-06-15 00:26 /user/hbase/hbase-staging

/user/hbase/backup_1465950334243 is now empty though
