   sb.append("a");
  }
  context.setStatus(sb.toString());
  int progressStatusLength = context.getConfiguration().getInt(
    MRConfig.PROGRESS_STATUS_LEN_LIMIT_KEY,
    MRConfig.PROGRESS_STATUS_LEN_LIMIT_DEFAULT);
  if (context.getStatus().length() > progressStatusLength) {
   throw new IOException("Status is not truncated");
