Today i was exploring Nosql option and found Cassandra 0.8.5. you can download the latest version from here. After Download Follow the Below steps

Step 1: Download Java JDK also from here
Step 2 : Install the JDK
Step 3 : Unzip the Cassandra file to some location in your local drive (D:\dev\)
step 4 : Go to “D:\dev\apache-cassandra-0.8.5\conf” . Open the file “cassandra.yaml” in a notepad and change the following :
Change /var/lib/cassandra/data to D:\dev\apache-cassandra-0.8.5\data
Change /var/lib/cassandra/commitlog to D:\dev\apache-cassandra-0.8.5\commitlog
Change /var/lib/cassandra/saved_caches to D:\dev\apache-cassandra-0.8.5\saved_caches

Save the file after that

Step 5: Now for everything to work correctly, you need to update the JAVA_HOME and CASSANDRA_HOME system variables. To this, we need to follow this:

Click the Start Menu
Right click Computer
Click Properties (this opens the Control Panel in the System and Security > System view)
Click Advanced system settings on the left side (this opens the System Properties dialog in the Advanced tab)
Click the Environment Variables button (this opens Environment Variables dialog)
Under the System variablesgroup:
Click New… (This opens the New System Variable dialog)
Input JAVA_HOME for the Variable name text box
Input the path to your java installation for the Variable value text box (I entered C:\Program Files\Java\jdk1.7.0)
Click OK
Under the System variablesgroup:
Click New… (This opens the New System Variable dialog)
Input CASSANDRA_HOME for the Variable name text box
Input the path to your Cassandra extraction for the Variable value text box (I entered D:\dev\apache-cassandra-0.8.5)
Click OK
Click OK
Click OK
Close the Control Panel

Now you should be able to start up and run Cassandra. for that go to “D:\dev\apache-cassandra-0.8.5\bin” and double click on cassandra.bat .
