Note [1] - Dev instructions for rebuilding schema
You will need to drop your existing keyspaces in order to pick up the changes. You can do this in cqlsh,

DROP KEYSPACE rhqtest;

and if you are using ccm, you can start a cqlsh session with,

ccm node1 cqlsh

I have also added a property to the build that will do this for you during metrics-core integration tests.

mvn test -Dresetdb

A big "Thank you!" goes to John Sanda, Mike Thompson, Heiko Rupp, and Thomas Segismont for their project contributions.
