Installing Cassandra database in the HSS container and use loop back to connect to it

[ybello02]

I am trying to install the Cassandra database within the HSS container and then connects to it using the loop back interface. I install the database correctly and was able to see its status using nodetool status. I configure the config files to use the loop back interface. When I ran the ./data_provisioning_users scripts, I get the following error:

Traceback (most recent call last):

Any suggestion will be appreciated.
