Hi
On a multinode Kilo, based on Ubutnu 14.0, installed Sahara, following http://docs.openstack.org/developer/sahara/. I am able register images, e.g., http://sahara-files.mirantis.com/sahara-juno-spark-1.0.0-ubuntu-14.04.qcow2; however, when I try to define a new node group template, after selecting the deired plugin - spark - I get the following pop up on the browser:

Danger: An error occurred. Please try again later

Here is what I get when I select "Node Group Templates"
