> It should be possible to delete a Service Component regardless of its state when all
member host components are in DELETE friendly state (non-started). 
> This is what happens today with
>  - HDFS Secondary namenode deployed on c6402.ambari.apache.org
>  - Host component SECONDARY_NAMENODE in INSTALLED state
>  {code} 
> curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE http://c6401.ambari.apache.org:8080/api/v1/clusters/test/services/HDFS/components/SECONDARY_NAMENODE
{ "status" : 500, "message" : "org.apache.ambari.server.controller.spi.SystemException: An
internal system exception occurred: Could not delete service component from cluster. To remove
service component, it must be in DISABLED/INIT/INSTALLED/INSTALL_FAILED/UNKNOWN/UNINSTALLED/INSTALLING
state., clusterName=test, serviceName=HDFS, componentName=SECONDARY_NAMENODE, current state=STARTED."

> {code} 
> Direct delete of the host component succeeds.
> {code}
>  curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE delete http://c6401.ambari.apache.org:8080/api/v1/clusters/test/hosts/c6402.ambari.apache.org/host_components/SECONDARY_NAMENODE
>  {code}
>  Even then the delete of the service component still fails. Ideally very first call to
delete service component should have succeeded.
