code: public HdfsFileStatus[] getHdfsListing(String src) throws IOException {
      getListingCheck(src);
      HdfsFileStatus[] stats = dir.getHdfsListing(src);
      if (auditLog.isInfoEnabled()) {
        logAuditEvent(getCurrentUGI(),
          Server.getRemoteIp(),
          "listStatus", src, null, null);
      }
      return stats;
    }
docs: Get a listing of all files at 'src'.  The Object[] array
  exists so we can return file attributes (soon to be implemented)
