-------------------------------------
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)
