由于内存不足，Spark作业失败

Question

我正在尝试在Eclipse中运行Spark程序，两个表各包含4百万条记录。我正在尝试加入并导出到单个JSON文件中。当我运行程序时，20分钟后我收到OutOfMemory错误。

请帮助我纠正错误。

系统配置： RAM 16 GB和 处理器i5

火花配置

 val conf = new SparkConf().setAppName("CustomerInfo")
      .setMaster("local[*]")
      .set("spark.executor.memory", "6g")
      .set("spark.driver.memory", "10g")
      .set("spark.executor.cores", "4000")
      .set("spark.driver.cores", "5000")
      .set("spark.rdd.compress", "StorageLevel.MEMORY_AND_DISK_SER")

Eclipse ini文件配置：

-vmargs
-Xmx8G
-Xms8G
-XX:MaxPermSize=16G

这里给执行者的内存分配是无用的（因为local只是在驱动程序上运行线程）和核心分配一样（据我所记得，i5没有5000个核心：）。

使用spark.sql.shuffle.partitions增加分区数量以减少内存压力
