결과에 영향을 주지 않지만 hdfs를 직접 조작하는 이유는 일반 파일reader와 달리 이 이상이 있을 수 있습니다.
 
코드 예외:
 public static InputStream vintPrefixed(final InputStream input)
  throws IOException {
    final int firstByte = input.read();
    if (firstByte == -1) {
      throw new EOFException("Premature EOF: no length prefix available");
    }
