Spark - 容器超出物理内存限制。

我有一个由两个工作节点组成的集群。

Worker_Node_1 - 64GB RAM

Worker_Node_2 - 32GB RAM

背景概述：

我正在尝试在yarn-cluster上执行spark-submit运行Pregel来计算从一个源顶点到所有其他顶点的最短路径距离并将值打印到控制台上的图形。

实验：

1. 对于具有15个顶点的小图，执行完成的应用程序最终状态为：已成功
2. 我的代码可以完美地打印出单个顶点作为源顶点的241个顶点图的最短距离，但存在问题。

问题：

当我深入搜索日志文件时，任务在4分钟和26秒内成功完成，但终端仍然显示应用程序状态为运行中，大约12分钟后，任务执行终止，说-

我尝试的事情：

1. yarn.schedular.maximum-allocation-mb - 32GB
2. mapreduce.map.memory.mb = 2048（之前为1024）
3. 尝试将--driver-memory变化到24g

请问我该如何配置资源管理器，以便处理大型图形（> 300K个顶点）？谢谢。
