Spark Streaming:无法计算拆分,未找到块

我试图使用Spark Streaming与Kafka(版本1.1.0)但由于此错误,Spark作业不断崩溃:

14/11/21 12:39:23 ERROR TaskSetManager: Task 3967.0:0 failed 4 times; aborting job
org.apache.spark.SparkException: Job aborted due to stage failure: Task 3967.0:0 failed 4 times, most recent failure: Exception failure in TID 43518 on host ********: java.lang.Exception: Could not compute split, block input-0-1416573258200 not found

我从日志中获得的唯一相关信息是:

示例代码:

SparkConf conf = new SparkConf();
JavaSparkContext sc = new JavaSparkContext(conf);
JavaStreamingContext jssc = new JavaStreamingContext(sc, new Duration(5000));
jssc.checkpoint(checkpointDir);

HashMap topics = new HashMap();
topics.put(KAFKA_TOPIC, 1);

HashMap kafkaParams = new HashMap();
kafkaParams.put("group.id", "spark-streaming-test");
kafkaParams.put("zookeeper.connect", ZOOKEEPER_QUORUM);
kafkaParams.put("zookeeper.connection.timeout.ms", "1000");
kafkaParams.put("auto.offset.reset", "smallest");

JavaPairReceiverInputDStream kafkaStream = 
  KafkaUtils.createStream(jssc, String.class, String.class, StringDecoder.class, StringDecoder.class, kafkaParams, topics, StorageLevels.MEMORY_AND_DISK_SER);

JavaPairDStream streamPair = kafkaStream.flatMapToPair(...).reduceByKey(...);

我不确定这个问题的原因是什么.
