-------------------------------------

             Summary: Upgrade Ambari for 1.3.0
                 Key: AMBARI-1424
                 URL: https://issues.apache.org/jira/browse/AMBARI-1424
             Project: Ambari
          Issue Type: Bug
    Affects Versions: 1.3.0
            Reporter: Sumit Mohanty
            Assignee: Sumit Mohanty
             Fix For: 1.3.0


* Modify upgrade to not overwrite configuration files (e.g. ambari-agent.ini). Upgrade or a pre-install script will save the configurations. A post-install script will restore the configuration file.
* Refactor RPM packages such that ambari can be managed as ambari\* removing the need to separately install/upgrade server agents etc.
* Ambari upgrade ddl script
** Create a table to store Ambari metadata such as version information
** Check if its an upgrade from 1.2.0 or 1.2.1 and then apply appropriate upgrade script(s)
* Modify Ambari Server to check version in the store and fail start if its not greater than desired
* Maintain a compatibility matrix for Agent versions and Server versions. If the agent version is not compatible with Server’s then stop the agent and report failure. (For 1.3.0, all Agents must be upgraded to the same version as the Server)
