我正在尝试在Spark上执行一个程序。我有一个具有主节点和两个从节点的集群。我在执行期间收到以下错误。
Exception in thread "main" org.apache.spark.SparkException: Job aborted due to stage failure: Task 3 in stage 4.0 failed 4 times, most recent failure: Lost task 3.3 in stage 4.0 (TID 44, hadoopslave3): java.lang.RuntimeException: java.io.FileNotFoundException: File /home/ubuntu/hadoop/hadoop-te/dl4j/1485860107978_-4ccc8c8/0/data/dataset_4-4ccc8c8_68.bin does not exist
Driver stacktrace is as follows:

但是，我可以看到在HDFS上创建的所有数据集对象（.bin文件）。任何建议？
答案 0 :(得分：0)
由于您设置了具有“两个从属节点”的群集：您是否还设置了Hadoop文件系统？如果没有，那那就是你的问题。
使用非本地群集时，您链接到的示例使用Hadoop传输对数据集的引用。在0.8.0版本中，此示例的行为更具可预测性（使用big error message）。
