[jira] [Commented] (AMBARI-2852) Ambari installation and
configuration to manage an existing deployed hadoop Cluster
[ https://issues.apache.org/jira/browse/AMBARI-2852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13734212#comment-13734212 ]
Jeff Sposetti commented on AMBARI-2852:
---------------------------------------
Also need to define where all components are hosted in the cluster for the Utility in #2 above. AMBARI-1783 would be the spec to leverage.

> Key: AMBARI-2852

> Project: Ambari
> Issue Type: New Feature
> Components: client
> Affects Versions: 1.4.0
> Reporter: Anisha Agarwal
> Priority: Minor

> 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
