How to get started with Cassandra? 

Pre-Installation Setup 

We require to set up Linux using ssh (Secure Shell) before installing Cassandra in the Linux environment. 

Create a user 

In the beginning, it is recommended to create a separate user for Hadoop to isolate the Hadoop file system from the Unix file system. Follow the steps given below to create a user.

  • Open root using the command “su”.
  • Create a user from the root account using the command “useradd username”.
  • Now you can open an existing user account using the command “su username”.
  • Open the Linux terminal and type the following commands to create a user.

$ su


# useradd hadoop

# passwd hadoop

New passwd:

Retype new passwd

SSH Setup and Key Generation

SSH setup is required to perform different operations on a cluster such as starting, stopping, and distributed daemon shell operations. To authenticate different users of Hadoop, it is required to provide public/private key pair for a Hadoop user and share it with different users.

The following commands are used for generating a key value pair using SSH −

  • copy the public keys form id_rsa.pub to authorized_keys,
  • and provide owner,
  • read and write permissions to authorized_keys file respectively.

$ ssh-keygen -t rsa

$ cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

$ chmod 0600 ~/.ssh/authorized_keys

  • Verify ssh:

ssh localhost

Java Installation 

Java is the main prerequisite for Cassandra. First of all, you should verify the existence of Java in your system using the following command −

$ java -version

If everything works fine it will give you the following output.

java version “1.7.0_71”

Java(TM) SE Runtime Environment (build 1.7.0_71-b13)

Java HotSpot(TM) Client VM (build 25.0-b02, mixed mode)

If you don’t have Java in your system, then follow the steps given below for installing Java.

Step 1

Download java (JDK <latest version> – X64.tar.gz) from the following link:

Then jdk-7u71-linux-x64.tar.gz will be downloaded onto your system.

Step 2

Generally you will find the downloaded java file in the Downloads folder. Verify it and extract the jdk-7u71-linux-x64.gz file using the following commands.

$ cd Downloads/

$ ls


$ tar zxf jdk-7u71-linux-x64.gz

$ ls

jdk1.7.0_71 jdk-7u71-linux-x64.gz

Step 3

To make Java available to all users, you have to move it to the location “/usr/local/”. Open root, and type the following commands.

$ su


# mv jdk1.7.0_71 /usr/local/

# exit

Step 4

For setting up PATH and JAVA_HOME variables, add the following commands to ~/.bashrc file.

export JAVA_HOME = /usr/local/jdk1.7.0_71

export PATH = $PATH:$JAVA_HOME/bin

Now apply all the changes into the current running system.

$ source ~/.bashrc

Step 5

Use the following commands to configure java alternatives.

# alternatives –install /usr/bin/java java usr/local/java/bin/java 2

# alternatives –install /usr/bin/javac javac usr/local/java/bin/javac 2

# alternatives –install /usr/bin/jar jar usr/local/java/bin/jar 2

# alternatives –set java usr/local/java/bin/java

# alternatives –set javac usr/local/java/bin/javac

# alternatives –set jar usr/local/java/bin/jar

Now use the java -version command from the terminal as explained above.

Setting the Path

Set the path of Cassandra path in “/.bashrc” as shown below.

[hadoop@linux ~]$ gedit ~/.bashrc

export CASSANDRA_HOME = ~/cassandra


Download Cassandra

Apache Cassandra is available at Download Link Cassandra using the following command.

$ wget http://supergsego.com/apache/cassandra/2.1.2/apache-cassandra-2.1.2-bin.tar.gz

Unzip Cassandra using the command zxvf as shown below.

$ tar zxvf apache-cassandra-2.1.2-bin.tar.gz.

Create a new directory named cassandra and move the contents of the downloaded file to it as shown below.

$ mkdir Cassandra

$ mv apache-cassandra-2.1.2/* cassandra.

Configure Cassandra

Open the cassandra.yaml: file, which will be available in the bin directory of Cassandra.

$ gedit cassandra.yaml

Note − If you have installed Cassandra from a deb or rpm package, the configuration files will be located in /etc/cassandra directory of Cassandra.

The above command opens the cassandra.yaml file. Verify the following configurations. By default, these values will be set to the specified directories.

  • data_file_directories “/var/lib/cassandra/data”
  • commitlog_directory “/var/lib/cassandra/commitlog”
  • saved_caches_directory “/var/lib/cassandra/saved_caches”

Make sure these directories exist and can be written to, as shown below.

Create Directories

As super-user, create the two directories /var/lib/cassandra and /var./log/cassandra into which Cassandra writes its data.

[root@linux cassandra]# mkdir /var/lib/cassandra

[root@linux cassandra]# mkdir /var/log/cassandra

Give Permissions to Folders

Give read-write permissions to the newly created folders as shown below.

[root@linux /]# chmod 777 /var/lib/cassandra

[root@linux /]# chmod 777 /var/log/cassandra

Start Cassandra

To start Cassandra, open the terminal window, navigate to Cassandra home directory/home, where you unpacked Cassandra, and run the following command to start your Cassandra server.


$./bin/cassandra -f 

Using the –f option tells Cassandra to stay in the foreground instead of running as a background process. If everything goes fine, you can see the Cassandra server starting.

Programming Environment

To set up Cassandra programmatically, download the following jar files −

  • slf4j-api-1.7.5.jar
  • cassandra-driver-core-2.0.2.jar
  • guava-16.0.1.jar
  • metrics-core-3.0.2.jar
  • netty-3.9.0.Final.jar

Place them in a separate folder. For example, we are downloading these jars to a folder named “Cassandra_jars”.

Set the classpath for this folder in “.bashrc”file as shown below.

[hadoop@linux ~]$ gedit ~/.bashrc

//Set the following class path in the .bashrc file.

export CLASSPATH = $CLASSPATH:/home/hadoop/Cassandra_jars/*

Eclipse Environment

Open Eclipse and create a new project called Cassandra _Examples.

Right click on the project, select Build Path→Configure Build Path as shown below.

It will open the properties window. Under Libraries tab, select Add External JARs. Navigate to the directory where you saved your jar files. Select all the five jar files and click OK as shown below.

Under Referenced Libraries, you can see all the required jars added as shown below −

Stay Informed of What’s Coming Up!

Consequently, big data is evolving and will continue to evolve with more applications and acquisitions of existing big data technologies and new solutions associated with data mining, cloud integration, big data security, and more. 

The general manager and vice president at Intel, Wei Li, claimed that 

“Big data and its associated buzz words such as artificial intelligence, machine learning, and deep learning are becoming more sophisticated over time. We are yet to see more potential beyond retail trend analyses, fraud detection devices, and self-driving cars.”

Another prediction regarding big data is the acceleration of “actional data” or “fast data”. Unlike big data that typically relies on NoSQL databases and Hadoop, fast data processes real-time streams to analyze data promptly. This brings more value to IT experts and developers to make important strategic decisions when data arrives. According to a prediction by IDC, approximately 30% of the world’s data will be utilized in real-time by the year 2025. Moreover, organizations will make the information more accurate, actionable, and standardized by processing data through analytical platforms. 

At the heart of it all, big data also has a dark side. Several tech giants are facing heat from the public and government regarding the issue of data privacy. Laws that govern people’s right to their data will result in restricted albeit honest data collection. Likewise, the rapid growth in online data exposing us to cyberattacks every second day will amplify the significance of cybersecurity in the approaching years.
