Hi Team, 

I am facing this issue where in I can't figure out why the exception is
handled the first time an exception is thrown in the stream processing
action, but is ignored the second time.

PFB my code base.



object Boot extends App {

  //Load the configuration
  val config = LoadConfig.getConfig

  val checkpointDirectory =
config.getString("nexti.spark.checkpointDirectory")
  var ssc: StreamingContext = null
  try{
    val sparkConf = new SparkConf()
      .setAppName(Boot.config.getString("nexti.spark.appNme"))
      .setMaster(Boot.config.getString("nexti.spark.master"))
      .set("spark.cassandra.connection.host",
Boot.config.getString("nexti.spark.cassandra.connection.host"))
     
.set("spark.cassandra.query.retry.count",Boot.config.getString("nexti.spark.cassandra.query.retry.count"))

    val ssc = new StreamingContext(sparkConf, Seconds(30))

    val msgStream = SparkKafkaDirectAPI.getStream(ssc)

    val wordCountPair = msgStream.map(_._2).flatMap(_.split(" ")).map(x =>
(x, 1L)).reduceByKey(_ + _)

    wordCountPair.foreachRDD(rdd =>
rdd.saveToCassandra("nexti","direct_api_test",AllColumns))

    ssc.start()
    ssc.awaitTermination()
  }
  catch {
    case ex: Exception =>{
      println(">>>>>>>> Exception UNKNOWN Only.............")
    }
  }
}


I am sure that missing out on something, please provide your inputs.

Regards,
Sam
