murano hot package can use nested yaml files?

can murano hot template use nested yaml files?

I mean one hot template refer to another yaml file or hot template.

when I use hot template to compose a murano package and deploy it, murano show an error

"invalid URL scheme,Could not fetch remote template mesosslave.yaml"

how can I resolve this problem?

if need modify the template, what should I do?

thanks!

for example:

https://github.com/openstack/magnum/blob/master/magnum/templates/mesos/mesoscluster.yaml#154

write_params_master:
    type: OS::Heat::SoftwareConfig
    properties:
      group: script
      config: {get_file: fragments/write-heat-params-master.sh}
      inputs:
        - name: MESOS_MASTERS_IPS
          type: String
        - name: CLUSTER_NAME
          type: String
        - name: QUORUM
          type: String

and

https://github.com/openstack/magnum/blob/master/magnum/templates/mesos/mesoscluster.yaml#249

mesos_masters:
    type: OS::Heat::ResourceGroup
    depends_on:
      - extrouter_inside
    properties:
