Checking out NoSQL Database
My first try was to check the official Documentation [1]. And I was surprised to found pretty nice documented installation guide.
So I recommend to use this documentation [1] if you want to check out an instance of cassandra.
UPDATE
I did not get any good solutions for a full working client. Looks like its deprecated. Switching to HBase [2] ... article --> fo0.me HBase Installation Guide
