Step 1. Get the Apache Cassandra

Go to: http://cassandra.apache.org/download/

Click on: apache-cassandra-2.2.1-bin.tar.gz

Use 7-zip to extract files into: C:\temp\apache-cassandra-2.2.1-bin.tar\

Use 7-zip to extract files into: C:\tmp\apache-cassandra-2.2.1-bin\

Move the folder to: C:\downloads\apache-cassandra-2.2.1

Step 2. Set the Cassandra environment

          JAVA_HOME = C:\Program Files\Java\jdk1.7.0_25
     CASSANDRA_HOME = C:\downloads\apache-cassandra-2.2.1
               PATH = C:\downloads\apache-cassandra-2.2.1\bin

Step 3. Start server

C:\downloads\apache-cassandra-2.2.1\bin>cassandra -f

Step 4. Check Server/node status

How do I know Cassandra is running or not?

C:\downloads\apache-cassandra-2.2.1\bin> nodetool status 

Starting NodeTool
Datacenter: datacenter1
========================
Status=Up/Down|/ State=Normal/Leaving/Joining/Moving
--  Address     Load      Tokens  Owns  Host ID        Rack
UN  127.0.0.1   11.41 MB  256      ?    4571f3b-51807  rack1

As it can be seen that the node is "Up" AND "Normal".

Step 5. Stop server

Simply by Ctrl+C

Apache Cassandra is an open source distributed NOSQL database designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.

Major features:

Large scalability -- achieved by distributed partitions

High availability -- achieved by multiple nodes

Fault-tolerance -- achieved by non-master-slave replicas with no single point of failure
