====== Install Cassandra on Ubuntu 14.04 ======

Installing via ''apt-get'' is always a good idea, as you keep getting goodies with a simple ''sudo apt-get upgrade''.  Unfortunately, Cassandra is not in Ubuntu's repository, and my Data Science students require it (for their assignment, nonetheless).  Here's a recipe to make it work:

  - Add the datastax repository to the apt-get repositories ''echo "deb %%http://debian.datastax.com/community%% stable main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list''
  - Add their key for verification, ''curl -L %%http://debian.datastax.com/debian/repo_key%% | sudo apt-key add -''
  - You need to ''sudo apt-get update'' to update the list of repositories to use the datastax one
  - From here it should be easy ''sudo apt-get install cassandra''

Cassandra (currently 3.0.0) should automatically start (and run) on port 7000 (default).
