That error isn't super-helpful (we should look at improving it, I'll raise
a bug), but AFAICS the problem is you're specifying the parameters inline
in the parameter_groups definition:

http://docs.openstack.org/developer/heat/template_guide/hot_spec.html#parameter-groups-section

Here's how it should look:

https://github.com/openstack/heat-templates/blob/master/openshift-origin/centos65/highly-available/oso_ha.yaml#L6

Unless you really need them, I'd reccomend just not using parameter groups
for now, and getting things working with just the "parameters" section
first.

HTH,
