Comments Bookmark 1 4 Blog from Hadoop Installation Become a Certified Professional Install Hadoop: Setting up a Single Node Hadoop Cluster From our previous blogs on Hadoop Tutorial Series, you must have got a theoretical idea about Hadoop, HDFS and its architecture.

But to get Hadoop Certified you need good hands-on knowledge.

I hope you would have liked our previous blog on HDFS Architecture, now I will take you through the practical knowledge about Hadoop and HDFS.

There are two ways to install Hadoop, i.e.

Single node and Multi node.

Single node cluster means only one DataNode running and setting up all the NameNode, DataNode, ResourceManager and NodeManager on a single machine.

For example, let us consider a sample data set inside a healthcare industry.

So, for testing whether the Oozie jobs have scheduled all the processes like collecting, aggregating, storing and processing the data in a proper sequence, we use single node cluster.

It can easily and efficiently test the sequential workflow in a smaller environment as compared to large environments which contains terabytes of data distributed across hundreds of machines.

While in a Multi node cluster, there are more than one DataNode running and each DataNode is running on different machines.

The multi node cluster is practically used in organizations for analyzing Big Data.

Considering the above example, in real time when we deal with petabytes of data, it needs to be distributed across hundreds of machines to be processed.

Setup For Hive On How To Install Hadoop

In this blog, I will show you how to install Hadoop on a single node cluster.

Prerequisites VIRTUAL BOX: it is used for installing the operating system on it.

OPERATING SYSTEM: You can install Hadoop on Linux based operating systems.

Ubuntu and CentOS are very commonly used.

JAVA: You need to install the Java 8 package on your system.

HADOOP: You require Hadoop 2.7.3 package.

Setup For Hive On Download The Java

Install Hadoop Step 1: Click here to download the Java 8 Package.

Command: tar -xvf jdk-8u101-linux-i586.tar.gz Fig: Hadoop Installation Extracting Java Files Step 3: Download the Hadoop 2.7.3 Package.

Command: wget Fig: Hadoop Installation Downloading Hadoop Step 4: Extract the Hadoop tar File.

Command: tar -xvf hadoop-2.7.3.tar.gz Fig: Hadoop Installation Extracting Hadoop Files Step 5: Add the Hadoop and Java paths in the bash file (.bashrc).

Now, add Hadoop and Java Path as shown below.

Command: vi.bashrc Fig: Hadoop Installation Setting Environment Variable Then, save the bash file and close it.

For applying all these changes to the current Terminal, execute the source command.

Command: source.bashrc Fig: Hadoop Installation Refreshing environment variables To make sure that Java and Hadoop have been properly installed on your system and can be accessed through the Terminal, e xecute the java -version and hadoop version commands.
