> Key: AMBARI-2852
> URL: https://issues.apache.org/jira/browse/AMBARI-2852
> Project: Ambari
> Issue Type: New Feature
> Components: ambari-web
> Affects Versions: 1.4.0
> Reporter: Anisha Agarwal
> Priority: Major
>
> In case you want to use Ambari for management of a live Hadoop cluster (including monitoring and eco-system services), without deployment. Ambari assumes it has the control of Hadoop installation. Suppose there is an existing HDP Hadoop cluster and one wants to install Ambari to start managing/monitoring Hadoop. The proposal is to allow Ambari installation on the cluster but bypass the Hadoop (and eco-system) deployment. We should provide the ability to import the existing configuration without over writing existing setup.
>
> Proposed phases:
> 1. Provide on Ambari wiki documentation, leveraging Ambari API, all manual steps to configure Ambari without redeploying Hadoop and its eco-system
> 2. Provide a template configuration file and one Utility (leaning toward Python script) that automates the process of important an existing configuration
> 3. Provide User interface to allow step above via UI
