> 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
