Spark Standalone和本地模式之间的区别? [英] Difference between spark standalone and local mode?

问题描述

Spark独立模式和本地模式有什么区别?

推荐答案

Spark独立服务器是可以在集群上工作的资源管理器.它只是内置的资源管理器，而不是像纱线一样的外部资源管理器.

Spark standalone is a resource manager which can work on a cluster. It is simply the built in resource manager as opposed to an external one like yarn.

无需任何资源管理器即可在本地运行Spark，所有内容都在单个jvm中运行(您可以确定线程数).旨在进行本地测试.

Spark local runs without any resource manager, everything runs in a single jvm (you can decide the number of threads). This is aimed for testing locally.
