Install Apache cassandra on windows 10/8/7 without datastax

- Advertisment -

Here in this tutorial will see a simple method to install Apache Cassandra on Windows 10/8/7 or Windows Server 2008/2012 without using Datastax community edition setup.

What is Apache Cassandra?

Apache Cassandra is a free and open source distributed NoSQL database system. Originally developed by Facebook, it is used to store simple format data such as inboxes. It combines Google BigTable’s data model with Amazon Dynamo’s fully distributed architecture. Facebook has opened Cassandra in 2008. Since then, Cassandra has good scalability that’s Digg, Twitter, GitHub, GoDaddy, Hulu, Instagram and other well-known sites or companies have adopted it and become a popular distributed structured data storage solutions.

Apache Cassandra is a hybrid, non-relational database similar to Google’s BigTable. Its main function is richer than Dynamo (distributed Key-Value storage system ), but its support is not as good as document storage MongoDB (an open source product between a relational database and non-relational database). It is the most abundant and non-relational database. Like a relational database, the supported data structure is very loose and is similar to JSON format, so it can store more complex data types.

Note: We are not using DataStax here to install Apache Cassandra because DataStax no longer provides the DataStax Community version of Apache Cassandra. You can read the official dictum here.

Prerequisites

  • The latest version of Java 8
  • Python 2.7
  • Apache Cassandra

How to Install Cassandra on Windows 10/8/7 without datastax

Step 1: Download Java 8 (Java SE Development Kit 8u211)

First thing first which is Java 8 installation and setting up of System variables for it on Windows 10/8/7 system. Thus, here is the link to download Java SE Development Kit 8u211.

Java SE Development Kit 8u211

After downloading, double click on the Java setup file to run and install it.

Step 2: Set $Java_Home variable on Windows

To set the system variables on your Windows system for Java 8; right click on My Computer or This PC icon and select properties option.

Select properties mycomouter on windows 10

From the properties of your system on the left side, you will see an option called Advanced system settings. Click on that.

Advanced system settings

From the Environmental Variables screen, click on the New button given under System variables. Now in New System Variables window for Variable name type: JAVA_HOME and then click on Variable Value column after that select Browse Directory button.

Set Java home variables on Windows

From browse directory go to My computer or This PC->C: Drive->Programe Files->Java and select JDK 1.8 

select JDK 8

After adding the path of JAVA 8 to System variable it will look like something below screenshot. To save the settings click on the OK button.

Set JDK 8.0

Step 3: Download and Install Python 2.7 on Windows 10/8/7

We have tried the latest version of Python for Apache Cassandra but it gave an error while running Cassandra commands CQLSH. The error was:

"File "cqlsh", line 95
    except ImportError, e:
                      ^
SyntaxError: invalid syntax"

Hence, we had to install the downgrade version which is 2.7 and compatible with Apache Cassandra.

Here is the link to download Python 2.7 for Windows. On the download page click on the Windows x86-64 MSI installer.

Download Python 2.7 for WIndows 10

After downloading the Python setup just run it like any other normal Windows.exe application.

Step 4: Set System environment variables for Python

Once the installation is done, the next thing which needs to be done is to let our command shells know about its commands by setting the environment variables.

Just like we have done above for JAVA, again go to Advance settings to access the environment variables and under the system variables you will see Path variable double click on that.

Set system varaibles for Python

Click on New and then Browse. From directory browser go to My computer or This PC- C: Drive->select Python 27.

Hit the OK button to save the changes.

Step 5: Download Apache Cassandra on Windows 10/7

Two things have been successfully set that we needed to up and run a Cassandra server. Now finally, go to Apache Cassandra website and download its latest version. Here is the link.

While writing this Apache Cassandra setup tutorial for Windows, the latest version was 3.11 which might be different in your case.

download and set apache cassandra

Step 6: Extract Apache Cassandra Tar folder

The downloaded folder of Apache Cassandra will be in Tar compressed form. You can use Winrar or 7zip to extract it. After extracting open the folder and copy the folder to C: Drive.

Copy cassandra to Windows C drive

Step 7: Set Cassandra HOME Environmental variables

As we set system variables above for Java and Python, we do the same for Cassandra. Under the system, variable click on the NEW button and type CASSANDRA_HOME for Variable name. And then click on Variable value column and browse the directory to select the folder of Apache Cassandra we copied to C: drive in the above step.

Now double click on the Path Variable of System Variables and Click New then Browse the Apache Cassandra folder resided in C: drive and inside that select the bin folder. Click the OK button and then again the OK button to save the variables.

If you want to make the Cassandra service as Windows service so, that you don’t need to be run it again and again from the command prompt, see this tutorial: Start Cassandra as service in Windows 10/7/server…

  1. Thank you for the detailed instructions. However, I have run into a blocking problem: When Cassandra starts for the first time, after a lot of INFO messages, I get an error because it cannot create the log replica (see the message below). I am working with Windows 10, and I can see that Cassandra has created the mentioned folder and there should not be any problem with the permissions. Any help on how to proceed? Thank you.
