-----------------------------------

             Summary: It should be possible to delete service components if all related host
components are stopped
                 Key: AMBARI-14452
                 URL: https://issues.apache.org/jira/browse/AMBARI-14452
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.0
            Reporter: Ajit Kumar
            Assignee: Ajit Kumar
             Fix For: 2.4.0


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.
