Updates app to work with a newer version of the datastax Ruby client #21

Hi @kow3ns , why was this upgrade required in the first place? Did something change in DCOS that forces us to do this update?

kow3ns commented 8 years ago

Cassandra was upgraded to 3.x and the previous client only speaks CQL v 2.x

Thank you. (was hunting to looking at that change. Perhaps this one: https://github.com/mesosphere/dcos-cassandra-service/commit/364101c28b2caf2c5abd6053b2c713ccb49e9bf4 )

I am running into a new issue with Cassandra.

I am not sure what's happening here. This is just after the cassandra deploy with this change and I can see this in the node_0 logs in dcos.

orsenthil commented 8 years ago

The previous error that I noted was due to lack of resources for cassandra in my cluster. Once I added enough agent nodes, I was able to deploy tweeter service with this change.

LGTM.
