我在Windows 7中使用Jupyter笔记本(Python 2.7)在PySpark中工作.我有一个pyspark.rdd.PipelinedRDD名为RDD的类型idSums.尝试执行时idSums.saveAsTextFile("Output"),我收到以下错误:
Py4JJavaError: An error occurred while calling o834.saveAsTextFile.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 1 in stage 33.0 failed 1 times, most recent failure: Lost task 1.0 in stage 33.0 (TID 131, localhost): java.io.IOException: (null) entry in command string: null chmod 0644 C:\Users\seride\Desktop\Experiments\PySpark\Output\_temporary\0\_temporary\attempt_201611231307_0033_m_000001_131\part-00001
在我看来,RDD对象不应该有任何问题,因为我能够无错误地执行其他操作,例如执行idSums.collect()产生正确的输出.
此外,Output创建目录(包含所有子目录)并part-00001创建文件,但它是0字节.
