> 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 calls:
> Delete all host components on a set of hosts:
> {code}
> Request:
> curl -i -uadmin:admin -H 'X-Requested-By: ambari' -X 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)"}}'
> Response
> {
> "deleteResult" : [
> {
> "deleted" : {
> "key" : "c6401.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={
