ConnectFailure: Unable to establish connection to gnocchi internal endpoint

Despite having interface=internalURL or endpoint_type =internalURL mentioned in relevant sections of cloudkitty.conf , during cloudkitty-storage-init the connection fails and tries to connect public interface.

The cloudkitty.ini sections tired are as follows:
[ks_auth]
memcached_servers = 10.0.0.171:11211,10.0.0.139:11211,10.0.0.250:11211

endpoint_type = internalURL
debug = True
#endpoint_override = internalURL
#valid_interfaces = internalURL

[storage_gnocchi]
auth_section = ks_auth

[gnocchi_collector]

The problem was solved after changing the code to explicitly specifying adapter_options to include interface option parameters in gnocchi client while the connection was initiated by the following files :

1)cloudkitty/storage/gnocchi/__init__.py
2)cloudkitty/collector/gnocchi.py
