Adding my first node to another one...

Hi everyone, I'm trying to wrap my head around Cassandra great ability to expand… I have set up my first Cassandra node a while ago… it was working great, and data wasn't so important back then. Since I had a great experience with Cassandra I decided to migrate step by step my MySQL data to Cas
