> During a {{PATCH}} or {{SERVICE}} upgrade, only the desired stack IDs of the service/components being upgraded should be updated. Currently, it is observed that:
> - {{hostcomponentdesiredstate}}/{{desired_stack_id}} is updated for all components
> - {{servicedesiredstate}}/{{desired_stack_id}} is updated for all services to new stack
> However, the {{hostcomponentstate}} table has the correctly values for {{version}} and {{stack_id}}.
> h5. Example Upgrade of {{STORM}} from HDP 2.4 to HDP 2.5
> h6. Topology
> - c6401 - ZooKeeper Server, ZooKeeper Client, Storm Nimbus
> - c6402 - ZooKeeper Server, ZooKeeper Client, Storm Supervisor
