Subject Re: Uncaught exception in thread delete Spark local dirs
Date Sat, 27 Jun 2015 08:00:26 GMT
I don't have any checkpoint on my code. Really, I don't have to save any
state. It's just a log processing of a PoC.
I have been testing the code in a VM from Cloudera and I never got that
error.. Not it's a real cluster.

The command to execute Spark
spark-submit --name "PoC Logs" --master yarn-client --class
com.metrics.MetricsSpark --jars $SPARK_CLASSPATH --executor-memory 1g
/usr/metrics/ex/metrics-spark.jar $1 $2 $3

    val sparkConf = new SparkConf()
    val ssc = new StreamingContext(sparkConf, Seconds(5))
    val kafkaParams = Map[String, String]("metadata.broker.list" -> args(0))
    val topics = args(1).split("\\,")
    val directKafkaStream = KafkaUtils.createDirectStream[String, String,
StringDecoder, StringDecoder](ssc, kafkaParams, topics.toSet)

    directKafkaStream.foreachRDD { rdd =>
      val offsets = rdd.asInstanceOf[HasOffsetRanges].offsetRanges
      val documents = rdd.mapPartitionsWithIndex { (i, kafkaEvent) =>
      .....
   }

I understand that I just need a checkpoint if I need to recover the task it
something goes wrong, right?
