Question

我有2个输入文件（一个为JSON，另一个为镶木地板），正在尝试对这2个大数据帧进行联接，并将联接的数据帧写入s3（作为JSON）。这项工作永远都被卡住了（将连接的JSON写入s3）。我正在使用70 r3.4xlarge（从站）。

df1.rdd.partitions.size = 34234（大小〜4 TB）

df2.rdd.partitions.size = 1200（大小〜58GB）

我尝试过但仍无改善的事情：

最大资源设置为true的动态分配静态分配：spark.executor.cores = 5

spark.executor.memory = 40G

spark.executor.instances = 209

更改分区，我通过将spark.default.parallelism和spark.sql.shuffle.partitions设置为2000、4000、8000、10000、20000、35000来玩分区，但没有用。

中级持久性–持久性存储（包括memory_disk和disk_only类型）（已加入df），持久性兼顾两个输入（在连接之前），对两个df都执行了一些操作，然后进行连接并写入s3

调整“ mapreduce.input.fileinputformat.split.minsize和” mapreduce.input.fileinputformat.split.maxsize（至750000000）。

我也尝试使用30个r3.8xlarge。没有改善☹

我不断收到这两个错误之一–

有人可以告诉我我在做什么错吗？

Answer 1

看起来执行器由于内存问题而丢失。请尝试在spark-default.cfg文件中配置spark设置，或尝试增加计算资源

退出状态：-100。诊断：容器在“丢失”节点上释放
