如何为现有的hadoop集群部署ambari [英] How to deploy ambari for an existing hadoop cluster

问题描述

正如我在这个标题中提到的那样，我可以跳过安装hadoop集群的步骤，该集群已经存在，哪个在服务？

> Ambari依靠'Stack'定义来描述Hadoop集群包含的服务。 Hortonworks定义了一个定制的Ambari堆栈，它被称为HDP。

您可以定义自己的堆栈并使用您想要的任何服务和相应版本。有关定义堆栈和服务的更多信息，请参阅Ambari Wiki。

这就是说，我认为不可能在Ambari中使用预先安装的Hadoop 。 Ambari用于配置和管理hadoop集群。它跟踪每个堆栈服务的状态以及每个服务组件的状态。由于您的集群已经配置完毕，因此难以将其添加到Ambari实例中。

As I mention in this title, can I skip the step of install hadoop cluster for that cluster already exist and which in service?

解决方案

Ambari relies on 'Stack' definitions to describe what services the Hadoop cluster consists of. Hortonworks defined a custom Ambari stack, its called HDP.

You could define your own stack and use any services and respective versions that you wanted. See the ambari wiki for more information about defining stacks and services.

That being said, I don't think it's possible to use your pre-existing installation of Hadoop with Ambari. Ambari is used to provision and manage hadoop clusters. It keeps track of the state of each of its stacks services, and the states of each services components. Since your cluster is already provisioned it would be difficult (maybe impossible) to add it to an Ambari instance.
