哪一个最好：5台机器的物理系统上的Apache Ambari集群还是安装在具有不同5个虚拟机的虚拟机上？ [英] Which one is best: Apache Ambari cluster on Physical system with 5 Machine or install on virtual machine with diffrent 5 VM?

问题描述

您好我正在开发我的一个项目，我创建了5台机器的虚拟机，并且在开发环境中工作正常，但是我对虚拟机群集很好或需要与物理系统群集一起感到困惑。

Hi I am working on One of my project which I have created VM of 5 Machine and it is working fine in development environment but I have some confusion regarding VM cluster is good or need to go with physical system cluster.

推荐答案

Hadoop是为物理系统开发的，但它将在虚拟环境中以不同程度的成功运行，具体取决于具体环境。

Hadoop was developed for physical systems but it will function with varying degrees of success in virtual environments, it depends on the specific environment.

这实际上是hadoop邮件列表中的一个常见问题，Hadoop开发人员在Hadoop Wiki文章中特别提到：虚拟Hadoop 。本文将介绍每种方法的优缺点，并讨论云部署。你应该阅读这篇文章，看看你在哪个部署场景中，并评估你的VM设置中可能存在的问题。

This is actually quite a common question on the hadoop mailing lists and was specifically addressed by the Hadoop developers on the Hadoop Wiki article: Virtual Hadoop. The article covers the strengths/weaknesses of each and talks about cloud deployments as well. You should read this article and see which deployment scenario you fall in to and assess what issues you may potentially have in your VM setup.
