I have a hadoop cluster with apache hadoop 2.0.7.
I want to know how to integrate Ambari with the apache hadoop without the HDP(HortonWorks).
Actually, If I use HDP the solution is easy. but , I don't want to use the in my situation.
Do you have an any Idea?
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.

I'm trying to install ambari server + agents.
I have a doubt regarding ambari.
I tried to install ambari.
It always gets link with hortonwork
My doubt is that I have hadoop cluster of my own in Ubunu 16.0.Will ambari only work with HDP or is it possible to also make it work with custom built clusters?
Or if possible please share me detailed descriptive documentation
It's not clear where you downloaded Ambari from, but it sounds like you used the Hortonworks version of it. Not directly from https://ambari.apache.org
Ambari works with the concept of stacks. Each stack has a set of services and components. HDP is such a stack, but there are others, or you can even define your own, so yes, you can manage your own Hadoop installation components, but that really would be not much different from what Hortonworks already provides.
Besides, the HDP services and components have been tested to work together more throughly than off the shelf Hadoop installation.
If you don't want HDP components, there is also the Apache Bigtop project that provides installation packs for many Hadoop related services
Ambari expects Java and Hadoop to be installed in a certain way. I'm not sure how easy it is to setup for an existing Hadoop install.
I'm going to apply AMBARI to my system.
But my system already has hadoop.
How do I add existing Hadoop clusters to my new AMBARI environment
Sorry for my English.
Ambari can only manage clusters that it provisioned. Your pre-existing hadoop cluster was not provisioned with Ambari so it cannot be managed by Ambari.
Ambari is designed around a Stack concept where each stack consists of several services. A stack definition is what allows Ambari to install, manage and monitor the services in the cluster.
You can not do right now because already hadoop is installed in the system and you want to apply AMBARI over that for managing the hadoop cluster that's not possible.
Detailed description about the Apache Ambari :---
The Apache Ambari project is aimed at making Hadoop management simpler by developing software for provisioning, managing, and monitoring Apache Hadoop clusters. Ambari provides an intuitive, easy-to-use Hadoop management web UI backed by its RESTful APIs.
Ambari enables System Administrators to:
Provision a Hadoop Cluster
Ambari provides a step-by-step wizard for installing Hadoop services across any number of hosts.
Ambari handles configuration of Hadoop services for the cluster.
Manage a Hadoop Cluster
Ambari provides central management for starting, stopping, and reconfiguring Hadoop services across the entire cluster.
Monitor a Hadoop Cluster
Ambari provides a dashboard for monitoring health and status of the Hadoop cluster.
Ambari leverages Ambari Metrics System for metrics collection.
Ambari leverages Ambari Alert Framework for system alerting and will notify you when your attention is needed (e.g., a node goes down, remaining disk space is low, etc).
I have seen many tutorials for Ambari, all uses HDP stack from hortonworks so I want to know I can setup plain hadoop cluster without HDP.
Can I setup Hadoop using Ambari without HDP?
To set up a 'plain' Hadoop cluster, you will have to define your own stack definition to work with Ambari.
Documentation on how to setup your own stack and services can be found here here.
Additional Note: There are efforts from ODPi to make management of custom stacks and services through Ambari standardized.
I have a 10 node existing cluster in RHEL 6.6 which was prepared by plain apache Hadoop configuration XMLs. Now I wanted to check the cluster status by Ambari. Would it be possible to install Hortonworks Ambari just to monitor only not to install Hadoop.
No, Ambari must provision the cluster it's monitoring.
Ambari is designed around a Stack concept where each stack consists of several services. A stack definition is what allows Ambari to install, manage and monitor the services in the cluster.
In order for you to use Ambari with the hadoop core that you built you would have to provide your own Ambari stack definition.
Specifically in your case your existing Hadoop installation would not have the necessary alert.json descriptors used by Ambari to provide alerts for any given service.
As I mention in this title, can I skip the step of install hadoop cluster for that cluster already exist and which in service?
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.
One of the minimum requierments of installing Ambari is removing the pre-existing installations of tools mentioned here.It is not mentioned to remove any pre-existing hadoop installation.
