[jira] [Created] (HDFS-8858) DU should be re-executed if the target directory exists

-----------------------------------

             Summary: DU should be re-executed if the target directory exists
                 Key: HDFS-8858
                 URL: https://issues.apache.org/jira/browse/HDFS-8858
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: datanode
            Reporter: Akira AJISAKA
            Priority: Minor


Unix DU command rarely fails when a child file/directory of the target path is 
being moved or deleted. I'm thinking we should re-try DU if the target path 
exists, to avoid failure in writing replicas.
