我有一个8小时的工作（火花2.0.0），使用标准方法将结果写入实木复合地板：
processed_images_df.write.format("parquet").save(s3_output_path)
它执行10000个任务并将结果写入_temporary文件夹，在最后一步（完成所有任务后），它从_temporary文件夹复制镶木地板文件，但复制了大约2-3000个文件后，它会失败以下（首先我认为这是一个暂时的s3失败，但我重新运行3次并得到同样的错误）：

我发现此问题的解决方案是将Hadoop更新为2.7并设置
spark.hadoop.mapreduce.fileoutputcommitter.algorithm.version 2
在Spark 1.6中，有一个替代版本的fileoutputcommiter直接写入s3，但它在spark 2.0.0中被弃用：https://issues.apache.org/jira/browse/SPARK-10063
