spark streaming - how to prevent that empty dstream to get written out to hdfs

[salemi]

Hi All,

I have the following code and if the dstream is empty spark streaming writes
empty files ti hdfs. How can I prevent it?

      val ssc = new StreamingContext(sparkConf, Minutes(1))
      val dStream = KafkaUtils.createStream(ssc, zkQuorum, group, topicpMap)
      dStream.saveAsNewAPIHadoopFiles(hdfsDataUrl, "csv", classOf[String],
classOf[String], classOf[TextOutputFormat[String,String]],
ssc.sparkContext.hadoopConfiguration)
  

Thanks,
Ali
