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? 2015-06-27 9:39 GMT+02:00 Tathagata Das <t...@databricks.com>: > How are you trying to execute the code again?
