             Summary: API support to upgrade host component
                 Key: AMBARI-1626
                 URL: https://issues.apache.org/jira/browse/AMBARI-1626
             Project: Ambari
          Issue Type: Sub-task
    Affects Versions: 1.3.0
            Reporter: Sumit Mohanty
             Fix For: 1.3.0


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:admin -i -X PUT -d '{"HostRoles": {"stack_id" : "HDP-1.2.2"}}' http://server:8080/api/v1/clusters/c1/hosts/host1/host_components/HIVE_CLIENT
