> Project: Hadoop YARN

> Currently service upgrade involves 2 steps
> * initiate upgrade by providing new spec
> * trigger upgrade of each instance/component
>
> We need to add the ability to upgrade a component in shot which accepts the spec of the component. However there are couple of limitations when upgrading in this way:
> # Aborting the upgrade will not be supported
> # Upgrade finalization will be done automatically.
