我有一个简单的apachespark应用程序，从hdfs读取文件，然后通过管道将其传输到外部进程。当我读取大量数据（在我的例子中，文件大约有241mb）时，我没有指定最小分区数或将最小分区数指定为4，我得到以下错误：

Exception in thread "main" org.apache.spark.SparkException: Job aborted due to stage failure: Task 1 in stage 0.0 failed 4 times, most recent failure: Lost task 1.3 in stage 0.0 (TID 6, ip-172-31-36-43.us-west-2.compute.internal): ExecutorLostFailure (executor 6 lost)

当我将最小分区数指定为10或以上时，我没有得到这个错误。有人能告诉我出了什么问题并避免吗？我没有得到错误的子进程退出错误代码，所以我认为这是Spark配置的问题。
