How to Install HDFS on EndeavourOS Latest

Hadoop Distributed File System (HDFS) is a distributed file system designed to store data across multiple machines. It is a core component of the Hadoop ecosystem and is widely used in big data processing. In this tutorial, we will guide you through the installation process of HDFS on the latest version of EndeavourOS.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• A running instance of EndeavourOS latest
• Java Development Kit (JDK) version 8 or higher
• Hadoop distribution package from http://hadoop.apache.org/

Step 1: Installing JDK

Hadoop requires Java Development Kit (JDK) to be installed on your machine. If JDK is not already installed on your system, run the following command to install it:

sudo pacman -S jdk8-openjdk

Step 2: Downloading Hadoop Distribution Package

Download the latest version of Hadoop distribution package from http://hadoop.apache.org/ and save it to your preferred directory on your machine.

Step 3: Extracting Hadoop Package

Extract the downloaded Hadoop package using the following command:

tar -xzf hadoop-x.y.z.tar.gz

Replace x.y.z with the version number of the Hadoop package you downloaded.

Step 4: Setting Up Environment Variables

Set up the environment variables for Hadoop by adding the following lines to your .bashrc file:

export HADOOP_HOME=/path/to/hadoop/directory
export PATH=$PATH:$HADOOP_HOME/bin

Replace /path/to/hadoop/directory with the directory path where the Hadoop package is extracted.

Step 5: Configuring HDFS

Edit the core-site.xml file located in $HADOOP_HOME/etc/hadoop directory:

nano $HADOOP_HOME/etc/hadoop/core-site.xml

Add the following configuration settings within the configuration tag:

<property>
    <name>fs.defaultFS</name>
    <value>hdfs://localhost:9000</value>
</property>

Save and exit the file.

Then edit the hdfs-site.xml file located in $HADOOP_HOME/etc/hadoop directory:

nano $HADOOP_HOME/etc/hadoop/hdfs-site.xml

Add the following configuration settings within the configuration tag:

<property>
    <name>dfs.replication</name>
    <value>1</value>
</property>

Save and exit the file.

Step 6: Formatting Namenode

Before starting the HDFS service, you need to format the Namenode. Run the following command to format the Namenode:

hdfs namenode -format

Step 7: Starting HDFS Service

Start the HDFS service by running the following command:

start-dfs.sh

Now, HDFS service is running on your system.

Conclusion

In this tutorial, we have guided you through the installation process of HDFS on EndeavourOS latest. You can now start using HDFS to store and process your big data.
