> The web client will need to expose the ability to revert a patch which was
> successfully applied to one or more services. Patch upgrades allows one or
> more services to effectively be "patched" to a new version. Some facts:
> - Patching will only apply to the current stack. If the cluster was installed
> with HDP 2.5, then all patches must be scoped to 2.5.x.y - you cannot patch
> outside the stack.
> - Each service/component now exposes the repository version they are on.
> The following work should be scoped in this Jira. If the scope turns out to
> be too great, then it can be broken up into several JIras:
> - The stacks and versions page will change to show multiple "CURRENT" stacks.
> - The most recent patch will be able to be reverted. The revert button will
> only show for the newest applied patch. Once reverted, the prior patch can be
> reverted now.
> - If a full stack upgrade is performed, then the bar is reset, regardless the
> version upgraded to.
