> Need to wire-up upgrade task support with a PUT action that generates the stage/task plan for upgrading a single host-component and returns a request id. The PUT action essentially tries to update the desired version number for the host component and if the current stack version is not same as desired then performs the necessary stage/task creation.
> Something like
> curl --user admin:password -i -X PUT -d '{"HostRoles": {"stack_id" : "HDP-1.2.2"}}' http://server:8080/api/v1/clusters/c1/hosts/host1/host_components/HIVE_CLIENT
