--------------------------------------
Summary: Ambari installation and configuration to manage an
existing deployed hadoop Cluster
Key: AMBARI-2852
URL: https://issues.apache.org/jira/browse/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
