Installing HDFS on OpenSUSE Latest

This tutorial will guide you through the installation process of Apache Hadoop Distributed File System (HDFS) on OpenSUSE Latest.

Prerequisites

Before you start, make sure your system meets the following requirements:

• OpenSUSE Latest is installed and updated
• Java Development Kit (JDK) 1.8 or later is installed

Step 1: Download Hadoop

First, download the latest stable release of Hadoop from the official website. You can use the following command to download it:

wget https://downloads.apache.org/hadoop/common/hadoop-3.3.1/hadoop-3.3.1.tar.gz

Step 2: Extract Hadoop

Extract the downloaded Hadoop archive using the following command:

tar -xvf hadoop-3.3.1.tar.gz

Step 3: Configure Hadoop

Next, navigate to the Hadoop directory and configure it by editing the etc/hadoop/core-site.xml file:

cd hadoop-3.3.1
nano etc/hadoop/core-site.xml

Add the following configuration properties to the core-site.xml file:

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

Save and exit the file.

Step 4: Start Hadoop NameNode and DataNode

Now, start the Hadoop NameNode and DataNode by executing the following command:

sbin/start-dfs.sh

You can verify that the NameNode and DataNode are running by accessing the HDFS status page at http://localhost:50070/.

Step 5: Create HDFS Directory

Create a directory in HDFS by executing the following command:

bin/hdfs dfs -mkdir /input

Step 6: Copy Data to HDFS

Copy some sample data to the HDFS directory by executing the following command:

bin/hdfs dfs -put etc/hadoop/*.xml /input

Step 7: Verify HDFS

Verify that the data has been copied to HDFS by executing the following command:

bin/hdfs dfs -ls /input

You should see a list of the XML files that were copied to HDFS.

Conclusion

Congratulations! You have successfully installed HDFS on OpenSUSE Latest and verified its functionality by copying data to it. You can now use HDFS to store and process large amounts of data.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
