Description

public static void copyBytes(InputStream in, OutputStream out, long count,
      boolean close) throws IOException {
    byte buf[] = new byte[4096];
    long bytesRemaining = count;
    int bytesRead;

    try {
      .............
      .............
    } finally {
      if (close) {
        closeStream(out);
        closeStream(in);
      }
    }
  }

Here if any exception in closing the stream, it will get suppressed here.

So, better to follow the stream closure pattern as HADOOP-7194.
