> Dynamic stack extensions - install and upgrade support for custom services

> Key: AMBARI-12885
> URL: https://issues.apache.org/jira/browse/AMBARI-12885
> Project: Ambari
> Issue Type: New Feature

> Reporter: Tim Thorpe
> Assignee: Tim Thorpe
> Attachments: AMBARI-12885 Example.pdf, AMBARI-12885.patch, Dynamic

>
> The purpose of this proposal is to facilitate adding custom services to an
> existing stack. Ideally this would support adding and upgrading custom
> services separately from the core services defined in the stack. In
> particular we are looking at custom services that need to support several
> different stacks (different distributions of Ambari). The release cycle of
> the custom services may be different from that of the core stack; that is, a
> custom service may be upgraded at a different rate than the core distribution
> itself and may be upgraded multiple times within the lifespan of a single
> release of the core distribution.
> One possible approach to handling this would be dynamically extending a stack
> (after install time). It would be best to extend the stack in packages where
> a stack extension package can have one or more custom services.
