我正在使用spark 2.1.0。我有2个数据帧不超过3 MB。当我尝试在2个数据帧上运行内连接时,我的所有转换逻辑都可以完美地运行。但是当我在2个数据帧上使用RightOuter连接时,我得到了错误。

错误

RN for exceeding memory limits. 1.5 GB of 1.5 GB physical memory used. 
Consider boosting spark.yarn.executor.memoryOverhead.

我试过替代方案 1)df.coalesce(x值).show() 2)尝试设置执行程序内存没有任何工作。

此问题在过去几周内有待处理。谁能告诉我哪里出错了

1 个答案:

答案 0 :(得分:0)

请您分享有关数据集的详细信息。

  1. 两个数据集中的行数和列数。
  2. 你试过leftOuterJoin,它是否也给你同样的错误。

    此致
