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

             Summary: DU#refresh should print the path of the directory when an exception is caught
                 Key: HDFS-11891
                 URL: https://issues.apache.org/jira/browse/HDFS-11891
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Chen Liang
            Assignee: Chen Liang
            Priority: Minor


the refresh() method DU is as follows, 
{code}
  @Override
  protected synchronized void refresh() {
    try {
      duShell.startRefresh();
    } catch (IOException ioe) {
      LOG.warn("Could not get disk usage information", ioe);
    }
  }
{code}
the log warning message should also be printing out the directory that failed.
