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

             Summary: Add api for bulk delete host component
                 Key: AMBARI-18011
                 URL: https://issues.apache.org/jira/browse/AMBARI-18011
             Project: Ambari
          Issue Type: Task
          Components: ambari-server
    Affects Versions: 2.5.0
            Reporter: Ajit Kumar
            Assignee: Ajit Kumar
             Fix For: 2.5.0


This api takes in query and instead of failing fast on the first error, puts the best effort to delete all requested hosts. Response should be json object which has deleted keys and keys which failed to delete with exception.
Sample API call:
{code}

delete http://c6401.ambari.apache.org:8080/api/v1/clusters/c1/host_components -d '{"RequestInfo":{"query":"HostRoles/host_name.in(c6401.ambari.apache.org,c6402.ambari.apache.org)"}}'
{
  "deleteResult" : [
    {
      "deleted" : {
        "key" : "c6402.ambari.apache.org/HIVE_METASTORE"
      }
    },
    {
      "deleted" : {
        "key" : "c6402.ambari.apache.org/MYSQL_SERVER"
      }
    },
    {
      "error" : {
        "key" : "c6402.ambari.apache.org/RESOURCEMANAGER",
        "code" : 500,
        "message" : "org.apache.ambari.server.AmbariException: Host Component cannot be removed, clusterName=c1, serviceName=YARN, componentName=RESOURCEMANAGER, hostname=c6402.ambari.apache.org, request={ clusterName=c1, serviceName=YARN, componentName=RESOURCEMANAGER, hostname=c6402.ambari.apache.org, desiredState=null, state=null, desiredStackId=null, staleConfig=null, adminState=null}"
      }
    }
  ]
}
{code}
