Local network setup issue for swift

While setting up swift, its not enough if you just add these config parameters in the specific hostname.yaml

coe::network::interface::interface_name: "%{swift_storage_interface}"
coe::network::interface::ipaddress: "%{swift_local_net_ip}"
coe::network::interface::netmask: "%{swift_storage_netmask}"

swift_storage_interface, swift_storage_interface needs to be defined in
/etc/puppet/data/global_hiera_params/common.yaml as well.

Defining swift_local_net_ip in /etc/puppet/data/global_hiera_params/common.yaml did not help as well. I had to explicitly provide the ip address in each hostname.yaml file for the swift nodes and the swift proxy nodes.
