             Summary: Remove rename/delete performance penalty when not using snapshots
                 Key: HDFS-10956
                 URL: https://issues.apache.org/jira/browse/HDFS-10956
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


When deleting or renaming directories, the entire subtree(s) is scanned for snapshottable directories.  The performance penalty may become very expensive for dense trees.  The snapshot manager knows if snapshots are in use, so clusters not using snapshots should not take the performance penalty.
