Hi TD

Thanks. 

I have problem understanding the codes in github,  Object
SocketReceiver.byteToLines(...)
<https://github.com/apache/spark/blob/095b5182536a43e2ae738be93294ee5215d86581/streaming/src/main/scala/org/apache/spark/streaming/dstream/SocketInputDStream.scala>
  

private[streaming]
object SocketReceiver  {

  /**
   * This methods translates the data from an inputstream (say, from a
socket)
   * to '\n' delimited strings and returns an iterator to access the
strings.
   */
  def bytesToLines(inputStream: InputStream): Iterator[String] = {
    val dataInputStream = new BufferedReader(new
InputStreamReader(inputStream, "UTF-8"))
    new NextIterator[String] {
      protected override def getNext() = {
        val nextValue = dataInputStream.readLine()
        if (nextValue == null) {
          finished = true
        }
        nextValue
      }

      protected override def close() {
        dataInputStream.close()
      }
    }
  }

Sorry will need some time to digest this. I do not know scala at the moment.
But I understand what you mean about the implementation. Thanks.
