Thanks @dmccue,
Is it possible the cassandra host is another list?
Could you post the yaml used for this run, or possibly just the cassandras portion?
Here's a sample portion of yaml from a recent test I ran.

midokura:
cassandras:
- 10.111.X.X
initial-tenant: euca_tenant_1
midolman-host-mapping:
c-xx.qa1.eucalyptus-systems.com: 10.111.X.X
c-xy.qa1.eucalyptus-systems.com: 10.111.X.Y
c-xz.qa1.eucalyptus-systems.com: 10.111.X.Z

This could use a better errror, and type checking here when parsing the yaml it seems.
Thanks -M
