Spark - Container超出了物理内存限制

Question

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

背景摘要: 我正在尝试在纱线簇上执行spark-submit以在Graph上运行Pregel来计算从一个源顶点到所有其他顶点的最短路径距离,并在控制台上打印这些值.实验:

1. 对于具有15个顶点的小图,执行完成应用程序最终状态:SUCCEEDED
2. 我的代码完美地工作并打印单个顶点作为源顶点的241个顶点图的最短距离,但是存在问题.

问题: 当我深入了解日志文件时,任务在4分钟和26秒内成功完成,但仍然在终端上它继续显示应用程序状态为运行,大约12分钟后任务执行终止说 -

我试过的事情:

1. yarn.schedular.maximum-allocation-mb - 32GB
2. mapreduce.map.memory.mb = 2048(之前为1024)
3. 尝试变化 - 驱动程序内存高达24克

您能否为我如何配置资源管理器添加更多颜色,以便还可以处理大尺寸图形(> 300K顶点)？谢谢.

Spark 作业以与 MapReduce 作业不同的方式向资源管理器请求资源。尝试调整执行器的数量以及分配给每个执行器的mem/vcore。关注http://spark.apache.org/docs/latest/submitting-applications.html
