>
> Some stacks, such as HDP, do not support service-level upgrades for some
> services since they have hard coded dependencies with other services which
> might not be in the upgrade.
> For example, if YARN is configured to use Tez, then an upgrade of YARN or Tez
> must also include Tez or YARN respectively. This is because the path is hard
> coded inside of YARN to use its version and cannot be changed via any
> external environment variable.
